Earn to die 2 is a little "endless runner" type of game where you drive a car around with simple and usable controls for iOS - a bit like Trials with tilting and things like that - and run over zombies, boxes, exploding barrels and make money doing so. You then use that money to upgrade your car in order to progress a little bit further and make more money, in order to - you guessed it - do the same thing, almost forever. There are a few flaws with ETD2, but I mostly had fun with it before it became repetitive and pointless.
Besides most Mario Kart games and TrackMania, I don't play racing games. Maybe it's because, like sports games, they emulate reality on a level that I don't find fun, maybe it's because I'm terrible at them, maybe it's because my gaming time isn't something I can just share between every game in existence, having tried NFS:MW, I think there is pretty good stuff in today's driving games, even tho I can't help but feel like they're missing part of their potential audience.
