Okay. The other thread I sort of messed up on, including some weird violent game choices. Here's a revised version with some of the suggestions you gave.
Damn! I forgot some. Here's the runner ups 1. Zen Bound 2. Koi Pond 3. Let's Golf 4. Littlest Pet Shop 5. Thomas the Train Game Pack
Blood and guns! In the dead bodies/min meaning of violence. Plus you can make mayhem to the music of choice. Preferrebly metallica or megadeth or something like that. =)
I say COD: Zombies, but only because of the shotgun. That said, none of the apps in the App Store are particularly violent... At least not compared to PS3 titles and Xbox titles.
