right now i'm playing Tiny Tower and Jetpack Joyride. I wish Shining Force would get updated for Ios6 but hopefully soon. And i may go with one of the Final Fantasy games soon if they go on sale (but with Square being tight wads probably not). I wish someone would put some classics rpgs like Breath of Fire or Skies of Arcadia on there...maybe one day.
Infinity Blade II, even though it is not optimized. Just picked up FIFA 13, it is optimized for iPhone 5 and is very addictive. Bad Piggies looks like lots of fun.
Well dude, as per my opinion: my favorite iPhone games are DrawRace Two and Dead Space. I would like to thanks to Innovative Games developed as part of iPhone Games Development; by the way great post.
