Half of those are cribbing from a specific game: Crossy Road. It's actually a pretty decent mobile game so it's not surprise it has rip-offs.
Funny enough, two of those apps icons ripped off assets from Minecraft. Totally won't get them in trouble, though. That's the magic of these mobile game stores: little to no moderation (unless your game is too politcal for Apple.)
I know you guys are Extremely Mad about mobile at all times, but you don't need to bump random year old threads because you couldn't find enough new threads to be Extremely Mad about mobile in.
