I figured since there's plenty of people self-isolating or out of work, I'd make up a little favourites list for mobile games, for little gems that stand the test of time (and boredom). With a little comment of why. Feel free to add your own list of stuff that stays on your phone, whatever genre, maybe with a little comment of why as well.
Favorite Idle Game:
Event Horizon : FrontierSo much fleet and ship customizability, so many actual options available, so much of a collectathon. It's just really, really good, and actually free to play as well. It's very hard to cap out this one, all grind is a noticeable improvement on your fleet, but perfection would take forever. It's still fun to try. It's also a fairly competent space shooter, but you can just autopilot it and watch all the explosions occur as your fleet massacres stuff. I've probably got 100s of hours racked up on this one. And if you do kick in some cash, you get a lot for it. You start out flying your ship, but the moment you find/put an autopilot on it, you can play it as a fun idle game (where you can immediately take control of your ship if you want too. The AI isn't that smart, but it's mostly a better pilot than you). You also never lose anything, everything is transferable to the next ship, unless you tried to make that ship a super-ship (you still keep all the stuff you put on the ship, it just has more slots to put stuff on, and you can chuck that ship to one of your AI commanders). 1-2 minute "click 1-2 buttons" game, repeat five times, *then* work out what to do with the grind. You now have more stuff. Rinse, repeat, enjoy. It's horribly fascinating just to watch, grind, or to tinker, or to personally fly in. It's that super-balance between "actual game" and "idle game" and "collectathon" that I've never seen in any other product. You can also murder top ranked player's starbases in PVP Arena (enemy is AI controlled) if you control your own ship (with enough energy, dps and energy-cheap cloaking to ignore their entire fleet and just invisible-missile-splat them), so it's not ptw in that way either. You just get lots of everything, paid or played. So does everyone else.
Favourite Roguelike:
Pathos: the Nethack CodexDoes everything a proper roguelike should do, with very differing classes and races to try, even party combos, but also has a very good interface on mobile. All the options, all the difficulty, with none of the obscure BS that nethack-likes often have. Pretty much the gold-star standard of how these things can be done. Hardcore, but still fun to play. Free-to-play as well.
Favourite Roguelite:
Cardinal Quest IIGives you all the fun cooldown-based ToME4-like rogue'ing you could want, but with a handy interface on mobile. I just like it better than the Pixel Dungeon derivatives. Makes you feel more powerful, while still being light and fun and with a slight difficulty curve. As mentioned below, kinda bridges the gap between roguelike and roguelite, and does it well. Not simple, but not hard to get into either.
Favorite Twin-Stick Shooter:
VirexianHas a cool retro/neon aesthetic, is fast paced, is hard enough to feel like you're doing stuff, but easy enough that progression isn't out of reach. Just a nice little adrenaline surge, which is what a twin-stick should give you. There's a free version, but the paid version is cheap too. Hard, but not that hard. Except when it is. And worth it.
Favourite Single-Stick Shooter:
Soul KnightHas auto-aim, so is single-stick. But with the range of shooty weapons (there's *so many* guns...), melee options, bosses, character classes, etc that makes it worth it to play a fair bit. Still has a certain skill level to play well, but is lighter and easier than Virexian above.
Favourite Turn-Based War Game:
Age of FantasyIt's not particularly well balanced (orcs are best, always), but all the races feel different enough and there's enough maps and strategic options that it's fun. Can get pretty damn hardcore in multi-player. This is a good thing. Oldskool turn/production war game, where taking a city 1-2 turns earlier is a huge boon, and movement/ unit skills/ attack ordering is paramount for higher level play. Overall foresight and unit match-ups are key, but so is the wonderful cascade of events on your own turn that lets you wipe enemies from areas of the map, even if it looked like you couldn't. Just a very good warlord/fantasy general type game, even if the graphics are shit.
Favourite Turn-Based Squad Strategy:
Templar BattleforceIt's a nicely polished game, with lots of options, and you can respec your characters to try out different things with no downsides. Very playable, very good. I don't like all of the mission pacing (I still haven't finished it though), but it does make it feel that the important decisions and turns really do count. One of those purchases that you feel that you got every cent from the purchase. Worth it. If you like wh40k, and having an awesome squad of "totally-not-space-marines", give this one a go. There's a free version, so you can try it out if you're not sure, but it's a good game from a good developer, so it's an easy buy once you've worked out that you do like proper squad based strategy games.
Favourite Business Sim:
M.U.L.E (on a NES emulator).
It's one of the grandaddies of the genre, and is still fun to play today. Just enough back-stabbing and market volatility that you have a plan, but you profit by decisions you make each round. But sometimes you just have to support the planet's colony to win, even if you could just crush everyone and profit immensely by doing it. Quick to play an entire game as well (which isn't something normally associated with business/ trading sims).
Favourite Action "RPG":
Stick RangerOK, it's not really an RPG, but you have a party of four people, they have swords and bows and magic and stuff, and you control them. I didn't know what else to call it. But it's here, it's on the list, and it should be on your phone. Whatever it is, it does it well. Has guns, punching, angels, priests and whips as well. There's builds and teams that are just plain for funsies, but you can make nearly anything work if you want. Or just skip a lot of the bits you don't like (often to your peril).
Favourite "actual" Action "RPG":
Dungeon QuestAgain, it's hard to say it's an actual RPG. But it's kinda like Diablo, the levels loop with +difficulty, and it's a collectathon, so that's kinda action RPG'y. Will you ever have the amount of stuff they talk about on the forums? To make that "essential" build? Hell no! But it's a really low-end/low-thought zap/slash 'em up, and while it gets pretty samey, and you get sick of the basic gameplay loop, what it does, it actually does pretty well. I have no friggen idea why the camera isn't zoomed out by about 50%. It's still strangely good for all that. You can pay for stuff, but you certainly don't have to.
Favourite "Easy" Top Scrolling Shoot'em Up:
OpenTyrianIt's old, I've finished it tonnes of times, but it's easy and fun. You can keep your weapons, you can keep your cash, you get super weapons (Sonic rear weapon whatever (once you've clicked on the side-panel thing during a level) and Plasma sidekick thingo are best-in-slot in many ways) at lvl1, but it's still a fun little adventure to play through. No, you can't get a better main weapon than the Laser. No, it doesn't matter too much by the time you do. Even your basic starter Pulse Cannon can loop the game. But it has secret codes, and side games, and a story, and discreet ship weapons, and all the other shit that a basic shoot 'em up doesn't need, but this one still has. It's free, it's good, and it's still one of the best games in the genre, even if you've got all the muscle-memory from the mid-late 90's to make it a cakewalk. It's still a very good game, even if it is pretty easy to finish repeatedly.
Favourite Screensaver Game:
Genghis Khan II (on a SNES emulator)
It's not a bad game once you download the manual, so you know what the little pictures mean. But it is awesome as a CPU vs CPU AI game, just to watch little EUIV/CKII-like wars continue on, forever, on your phone. Japan is OP as hell, and usually "wins". Samurai everywhere. There's a coding glitch that means the AI can't win/conquer the globe (without *very* unlikely events occurring in the final turn. It can happen, but it almost certainly won't most times). So it goes on forever. Still makes for an excellent screensaver. Think of it like "watching" a 5-day cricket test. You just check up on the scores, and who's in, from time-to-time. But on a Civilization/ Europa Universalis/ Crusader Kings style playing field and wicket.
Favourite App:
Magic DosboxIt lets you play damn near any dos/win3x/win95-98 game on your phone. And you can setup incredibly versatile and powerful touch screen interfaces for them. Another one of those things where the paid app it actually worth it. Has a large'ish user community making templates for games, so you might not have to do a single thing other than play your favourite games from yesteryear on your phone (take a look here, work out if you like any of these games, and if it's worth $5 to you to be able to play them properly on your phone:
http://magicbox.imejl.sk/forums/forum/mgc-files-sharing/). There's even stuff for X-Wing and TIE-Fighter, Elite 2&3, etc, and they're all better 3D space combat/ possibly trading sims than anything on the playstore, so this is a cover-all. I even made a Stars! win3x thing for it (which is an old/ crunchy 4X space game), and it works great. It can do anything.
Favourite File Manager:
ES File ExplorerIt does everything a file manager on your phone should do, and a bit more as well. Is it Chinese government spyware? Does it have an ad in a foreign language now when you load it? Is it still a really good file manager? Probably, yes. Has a download manager integrated, and can let you "open as" a tonne of file types for any other apps you have on your phone. Can also resume dropped downloads, assuming the file server on the other end still has it as an open/possible channel. Makes your phone a lot more like a PC, so is a good thing. I'm lost without it these days when I buy a new phone.
Favourite file compressor:
RARIt's just better than anything else, faster than anything else, supports more formats than anything else, and integrates easily into file managers (like the one above). Has a reasonably long "recent directory to unzip to" list, so whether you're doing an emulation binge, want to sort your dosbox'ing easily, are doing an MMDarchive model/scenary-type directory run, or just need a thing that can unzip nearly anything quickly, it can do it (even on batch runs) well. Good and free.
Favourite "other" App:
PocketMQOIt's because of boobs. Dancing anime boobs. I'd love to say it's because I love music, or Japanese culture, or MikuMikuDance, or that I am just a creative soul, but I'd be lying. It's because of MMD boobs. They're great. And it's free. Wash your hands though!
(yeah, it can get worse)
Best "isolation" Web Browser:
Opera ClassicDid you know that an incredibly old web browser doesn't have any native .mp4 support? Did you also know that all of Pornhub's 320x240 previews are in .mp4 format, if you press that button? And that this web browser just gives up, and sees it as a file, and downloads it? And so, free porn for all! (even at very low resolution). No account needed! It's still free! It's like you're in Italy, but you're not dying of the most recent plague!
Wash your hands, thoroughly and regularly...
(also works fine when there isn't any plagues, and has for years. You might need to reload some pages repeatedly for it to work though. It doesn't do proper modern security protocols well either. It will work, but it might take a few page reloads. They don't have to hand out free accounts if you know what you're doing. Bless them that they did though
)
(I'll probably add to this list as I think of them. But make your own, so we can all discover those hidden gems in the app/play store, or wherever on the web)
