InMomentumSure, it's minimalistic in looks; sure, it may be a bit of a Mirror's Edge knock-off; sure, it's a platformer from hell on harder difficulties; but damn, if it isn't fun. I got it off a bundle, and actually looked forward to it from what I saw.
This is a freerunning playground (actually, the level Freestyle is a better example) that you can absolutely bolt through. No guns (actually, it's more a checkpoint gun that's made to knock out gates that make levels harder to go through. And in multiplayer, it briefly slows your opponent(s).), no monsters, no other goals but the finish line/gate.
Yes, I spent over an hour here. What of it? It's my playground.
Took me 15 whole seconds to land at the absolute bottom of the level (that's landable) at terminal velocity. AAAAAaaaaAAAAaaaAAAaaa!!!! has longer falls than that.
I think most reviewers are Graphics=Good Game, and are also likely under-/un-skilled platformers/gamers. Then again, I'm also the opposite end of that spectrum (I don't give as much a crap about graphics (8-bit era, I started in; Commodore-64 FTW!), and I'm surprisingly more competent than initially expected; and a tad suicidally confident at times.), but at least I'm open-minded to it, and other newer games and indie games in general. Plus, despite being minimalistic, it's surprisingly immersive (you can sorta feel your speed without looking at the speedometer; which helps with timing a good jump). So much, that I want it to be Oculus-Compatible. Being made in Unreal Engine 3, I hope it's standard to the point of being an option (3rd-party, or provided by devs).
In similar vein:
CloudbuiltThis game is also pretty damn fun; though reviews are scattered since the sales (Some seem to not be fans of challenges or Sonic/Megaman). Think InMomentum, except instead of minimalistic, it's cel-shaded beauty. And instead of building up speed the normal way, you have a jetpack, that assists in wallrunning (vertically and horizontally), walljumping, and jumping long gaps. Oh yeah, and you have a blaster like Mega Man (though no robot masters to snag abilities from) to assist you through levels, knocking out robots, or blasting gates apart. Storyline involves being post-coma after an accident or war, and this is your path to recovery; this game (Sounds similar to IM's initial storyline (all there in the manual), before they tossed it, and dedicated it to freestyle/freerunning racing). Fuck what people say, this game is pretty damn fun (and frustrating in certain levels), though a bit more intense graphically than InMomentum, but the extra juice used is worth it, because damn, is it pretty.
EDIT:
One major gripe I would agree with about InMomentum is it's lacking playerbase to multiplay against. Negative reviews don't help this one bit. Quit your bitching, newbies, and stop ruining it for the rest of the more competent ones that DO actually want to race ninja-style. Go back to Skyrim, DOTA, or WoW, or some other popular location that accepts your conformist nature (Sorry to hipsterfy there for a bit; but this behavior still pisses me off. Call me an old man, but really...). I still check from time to time to see if anyone's on, nonetheless.
EDIT EDIT:
Speaking of lacking multiplayer games that need players again:
Super Laser Racer (Or as I have been commented: "The most videogame named videogame ever.")
Super Mario Kart/Wipeout (Death Race) meets Tron (vector graphics), viewed from above (2D). More fun than it looks and sounds, and has some pretty nifty music to it. Reason for lacking popularity. As you'd guess, vector-style graphics aren't cool. Not hip. Not SWAG. Not chill. Not "bad". Not (INSERT LAME-PAST-IT'S-PRIME SLANG/LINGO). That, and like I also said before, maybe they suck so terribly at the game, they downvote because victory isn't spoonfed to them.
I play this with my brothers online every other week, and it's hilarious, fun, and difficult most the time. We need Bay-12 servers for this game. It demands it. Toss in Steam Chat, Google+, or Teamspeak, or anything else that can allow for vocally/verbally abusing other players as you get mauled to death in the game. The unrefined anger from other players (and sometimes your own) is half the fun of this game.
