Epic iPhone OS games

A list of games I officially recommend:

• Vay: A port of the Sega CD classic. A must have for JRPG fans who don't mind going retro
• iFighter: A vertical scroller shmup game, reminiscent of classic shmups
• Pac-Man: Wakka wakka wakka wakka...
• SkyFighter: Like iFighter, but I found it to be less of a Bullet Hell. A free demo of both is available
• Baseball Superstars 2009: Fun with RPG-like elements and lots of unlockables, but doesn't make much use of iPhone touch and tilt capabilities, reverting to rendering buttons on the screen
• Star Trigon: Quick fun, though the controls can get tricky, and the game does get hard fast
• GeoDefense: A tower defense game. Really really hard and fast paced but lots of fun and very challenging.
• Fieldrunners: Another tower defense game, plays differently from GeoDefense, has a more slower pace.
• Topple: The idea is to stack different shaped blocks without them being toppled. Just buy it.
