Right, so there are lots of good free games out there, but you have to wade through piles of crap to find a game that's well, actually a game. I don't mean games like 'fall down' or 'buy stuff to use in missions, never actually so anything' kind of games, but like RPGs and shooters. Real games. Some of them that I've found are: AurumBlade Dawn of Magic GalaxyOnFire And GT Free+
This comes up often and here's a thread with a pretty good list of always-free games. It doesn't have most new games, but it is still a great list nonetheless. http://forums.toucharcade.com/showthread.php?t=99986
