I tried a few games recently...
Resident Evil - DegenerationOh my, the background music scared me...

Thrilling music effect, certianly a nice game, but just too heavy for me. Killed a few zombies, the virtual D-Pad is not so smooth to my liking.
Brother In Arms - Hours Of HeroesI like this game very much, the graphic is awesome, the gun-shooting sound is so real, I feel like I am in the war!

The trial version ended so soon, grrrr, certainly make me feel like buying the original copy.
Golden Miner 2I like Gold Miner game since PC version. A light game, with less-thinking, straight-forward, interesting graphics, so I made my second purchase at USD1.99 after I bought Face Fighter

Also tried a handful of games such as Cooking Mama, Kids Zombie, Brain Free, Tap Tap, Cooking Dash, Sushi Chain, Oh Yeah (the farting game, lol), UNO, Tower, Live Porker, 21 Pro, Lemonade, Pool Star, Blades and many more. Love every bits of my iPhone!
true bro..the BIA is awesome..im playing it..and got addicted to it already..
