Game Idea: Europa Explorer
« on: July 31, 2010, 11:18:01 am »

Alright, so by chance my brain accidentally mixed my memories of Ecco the Dolphin and Motherload, which then got me to thinking about exploration games.

Now, I don't like 'fantastic' exploration games, which take place in a fairy tale world which is "like Earth but different". There's a lot of fun to be had exploring, but in order to procure that fun for the player, I think it's best to introduce them to a truly alien world, where they honestly can't tell what they're going to find next. It's a mixture of curiosity and intrigue that needs to be pulled off successfully, and I feel that Motherload was an excellent exploratory experience. Now, I say that it was excellent because it had me going further and further down into the crust of Mars, and with each few hundred feet I went, my surroundings became progressively more and more alien, and I wanted to dig deeper, not only to accrue more valuable gems, but to ultimately find out what was at the bottom of this subterranean world I was diving into one block of dirt at a time.

Hell, when I tried out Minecraft, I had fun just randomly digging down and finding hidden caves!

Now, I mentioned Ecco the dolphin earlier, because I remember being frighted by that game, just because I was so young at the time that the under sea world was so alien and frightening.

Now, I started thinking of a game which combines my love of exploring alien environments, with my natural fear of the undersea world.

And what I got was Europa Explorer.

Now, as you may or may not know, Europa is a moon of Jupiter that is completely covered in frozen water. The world of Europa Explorer will take place in a hypothetical future where super-science has enabled humanity to terraform Europa, and transform it into a regular ocean world. The beginning of the game will take place just as humanity is just starting to colonize it, with the vast majority of Europa's depths an unexplored mystery to everyone. The main character would be a freelance undersea explorer, traveling all over Europa to suspected spots of interest, and then using his personal submarine to dive into the depths. The object of the game would be to find interesting things, and then sell the information so that you can upgrade your boat or submarine, and gain access to more areas in a metroid-esque fashion.

Due to the fact that the exploratory part of the game makes up the vast bulk of the gameplay, it's necessary that it be interesting at worst, and awe-inspiring at best. To facilitate that idea, not only would the underwater landscape need to have alot of thought put into it, with things like sunken spaceships and other vessels to explore, but impossibly deep Marianas Trench-esque features would need to be present, and active underwater volcanoes that are constantly spitting smoke and sulfur. Also, due this Europa, the game would have free license to contain as many bizarre and alien aquatic creatures as could be imagined. There could be things like giant serpents that resemble the Sandworm from Dune, or plant-like creatures that that grab anything that get near them. To make things educational, it could even contain the more outlandish real creatures, like giant jellyfish, or translucent fish that glow in the dark. No matter what though, the underwater world should always be vibrant and interesting.

I feel that the underwater world should have a great deal of mystique to it. To simulate actual diving, the submarine would encounter a great deal of life near the surface, but as the submarine descends more deeply, things gradually get more dark and more lifeless, and then eventually the sub is forced to use it's personal flood light in order to see at all (the flood light would be manually controlled by the player, of course), and while you'd encounter less typical fish, everything would become alien to the senses.

Man, I'm sorry if I'm using the same words over and over, but my internet went down AS I was writing this, and I can't access a thesaurus like I would usually when writing these gigantic things.

Also, I just thought, that in addition to the submarine, there could even be a scuba-diving mode. Where the player would be able to exit their sub and then explore the surroundings in person, or even be able to get into smaller places. For example, upon arriving at a sunken ship, the player can get out of their sub, and go in and explore it! I think that would be cool.

Now, to add to the mystique, there should also be an element of danger. Now, for the most part everything could be peace, but there could be some dangerous parts to the game that could spell game over for you if you're not careful. It doesn't have to be hostile life attacking you either, it could be unexpectedly strong currents pushing you into unknown areas, you sub not being built for extremely deep diving and slowly being crushed by water pressure, or dumbly driving into the opening of a volcano.

About the upgrade system I mentioned earlier, it could feature a whole lot of different things, to allow the player to play through the game in any order they want. For example, you could buy upgrades to your submarine so you can dive more deeply before you get other things, or you could get upgrades to your boat, like an ice-breaker so that you can travel to colder areas that would ordinarily be restricted by the ice. Things like that.

I was thinking, that if you could visit sunken vessels or even crashed spacecraft, then it would probably be pretty cool to be able to salvage things from those wrecks, like things you can use to augment your equipment, or sell for more cash.

I am mentioning stuff like "Selling" and "Upgrading", so I guess there'd have to be stores for those activities. There could be cool floating cities at certain hot spots on Europa, which would be more heavily populated, and allow you to buy, sell, gather info, or whatever.

One problem I have imagining though, is that to be scientifically accurate I'd have to include the fact that Europa's about the size of the moon, which would make some significantly less gravity everywhere, and I'm not sure how to represent that in the game world, let alone an undersea world.

Also, there's the fact that Europa's day/night pattern would be pretty different from that of Earth's, since it's not only orbiting the sun, but also orbiting Jupiter. If you were standing on a boat on Europa, how big would Jupiter in the sky be? What would the day/night cycle be like? Should my character be able to jump from one end of the boat to the other, due to the decreased gravity? These are tidbits of research I haven't done, but would be necessary to ensure greater scientific accuracy in such a game.

I just thought I'd write this stuff down, what do you guys think?

Neat-o idea.

From my calculations, Jupiter would be about 16 arcseconds in size when viewed from Europa. In layman terms, Jupiter's apparent size would be less than 1% of the Moon's... it would be a tiny speck.

Coming up with some more calculations...

The gravity on Europa is about 15% of Earth's gravity, so you would weigh 15% of what you do on Earth.

This would also affect diving itself... the pressure 6.7 km below Europa's ocean would be roughly the same as 1.0 km below Earth's ocean. Disregarding temperature, one could go 6.7 times deeper on Europa compared to Earth.

Lord Dakoth, your calculations are wrong, I'm afraid. Jupiter's size should be around 13 degrees, or 25 times as large, diameter wise, as Moon or solar disc.
Spoiler: calculations (click to show/hide)

A day on europa takes roughly three and a half Earth-days. A few notes though:
Europa is, like our Moon with Earth, tidally locked with Jupiter, meaning that it has the same side always facing the Jupiter.
Jupiter and it's satellites are quite far away from the Sun. Apparently, it's moons recieve more energy from the planet than they get from the star. That would probably bear consequences for any possible life on Europa, as the side facing Jupiter would always recieve more heat than the far side.

As for the marine life seeing any light at all, it's highly unlikely. Sun is very dim out there, Jupiter radiates in infrared, and there's some very thick(like, kilometers thick) ice covering the surface. You can get around it by having your submarine "see" using a sonar or somesuch device.

The surface temperature is very low, -150, - 220 degrees Celcius. Deep down, underneath the ice, however, the temperature should stay around 4 degrees Celcius, due to water's anomalous density change at that temperature.

I wouldn't worry too much about lower gravity. The marine lifeforms wouldn't notice anyway, as they're fully immersed and "feel" weightless in water. Only your sub's commander could feel uneasy walking aroung the vessel, but you probably wouldn't want to include that in the game anyway.

Your idea makes me think of one s-f novella I once read. It concerned biologically(mostly surgically) altering human subjects to allow them to live in the environments of alien worlds. It was pretty harrowing, the subjects being orphaned kids, and the procedures very invasive.
Still, it could be interesting to have such trans-humans explorers instead of a rather cliche submarine.

The only real problem I have with the idea is adhering to a realistic impression of Europa.  By rights, it'll be alien sure, and more so than just Earth's ocean floor.  But how alien can you really make it, and still be anything like realistic?  I'm not sure what else you could do without just going whole hog and remaking Starflight, underwater or otherwise.

Just to inject myself, I had an idea like this recently, inspired more by Herocore; it would be focused on spelunking and exploration of an alien cave-world, with gameplay centered around manipulation of light, momentum, and gravity, and relying on finding materials and crafting tools.  I like submarines more though, and Ecco the Dolphin was a headtrip in its time.

Oh, fml. Arcdegrees. I was thinking arcseconds for some reason.

On another note... would the player be the only explorer, or one of a small team of explorers, or one of hundreds of maliciously competitive explorers subcontracted by NASA? I think that having some good ol' backstabbing competition could definitely spice the game up a bit, but it might also take the focus away from exploration.

That's an extremely interesting thing to consider. The game could start on the side always facing jupiter, but could then eventually steer the player into the eternally night, significantly colder dark side of Europa.

The only real problem I have with the idea is adhering to a realistic impression of Europa.  By rights, it'll be alien sure, and more so than just Earth's ocean floor.  But how alien can you really make it, and still be anything like realistic?  I'm not sure what else you could do without just going whole hog and remaking Starflight, underwater or otherwise.

I'm sure that, given the environment, a fair number of unique creatures could be crafted. For example, I think most of the fish that you'd find though would be completely blind, having not evolved eyes in their eons of living in an ocean underneath kilometers of ice. This would necessitate that all the various lifeforms have other ways of detecting things around them, which would be anything from systems of branch-like antennae tentacles, or elaborate bio-thermal sensory organs, or extremely delicate flagellum* covering their bodies that detect movement

I think that having some good ol' backstabbing competition could definitely spice the game up a bit, but it might also take the focus away from exploration.

As I said, the main character would be freelance. Gathering info on the sea floor, finding mineral or natural gas deposits, selling the info to the government or some interested corporations, or maybe even taking odd jobs from the denizens that inhabit the floating cities. There could even be things like attaching flotation devices to sunken objects and then forcing them back to the surface, or jobs that would entail the player having to scuba into a cave dark undersea cave in order to get an item of importance.

Now, I don't think that the player should be alone in his quest, no, it'd probably be best if he had an NPC partner to assist him. I can more than imagine a gruff sea captain that would provide dialogue to the main character when nothing interesting is going on, and provide interesting bits of knowledge on everything the player discovers. This way, you could mentally keep the player occupied, provide some personality to the characters, and allow the game to be educational in the process.

* = (I know flagellum probably isn't the right word for this example, but I simply can't think of what the correct word would be)

Europa is covered in cracks and chasms. What if, hypothetically, an agency drilled their way to the liquid and set up a series of small underwater supply stations connected to biodomes on the surface? That way you wouldn't have to break away from the ocean unless you really needed something odd that you had to order from one of the main bases.
