As I am interested in iPad Games Development, I am always enjoying and, My Favorite iPad Apps Games are below:
American Ball - Games
Angry Birds - Games
Zombie Cafe - Games
American Ball - Games
Popular Science - Entertainment
add Fieldrunners 2 to my list. I've never really liked tower defense games, but this one has me hooked! I will try more of that "genre". Also about to get the new Rovio (angry birds) game, Bad Piggies.
