Brothers in Arms 2 Free is cool. (never played the franchise before, but it plays a lot like the ground battles in the original Call of Duty game)
Sky Gamblers: Rise of Glory (WWI Combat flight sim, there are others in the series featuring fighter jets and WWII-era stuff but they seem exclusive to iOS at the moment)
Skies of Glory (similar to Sky Gamblers: Storm Raiders but with less features, aka, no virtual cockpit, graphics are a bit dated)
Deer Hunter Challenge (great way to blow a couple hours)
In the casual dept. there are clones of some games, such as Bubble Mania (clone of Bust-A-Move) Farm Story (Farmville clone) City Story (Cityville clone) Dragon Story (seems to work like virtual pets, but has the evolution style of Pokémon, you really need to see it to believe it) and one of my favorites, Men in Black 3
