Sim Cities and Strategies

SimCity: It's SimCity, and it's in the palm of your hand (technically, it's SimCity 3000, but you get the idea). This spot-on re-creation operates surprisingly smoothly, providing everything from advisors to disasters--all that you'd expect from the classic PC game.

Fieldrunners: Hands down, this is one of the best and most polished iPhone games going. If you're a Tower Defense fan, check this out.

Lux: Remember the board game Risk? That's what you have here.

Zombie Attack: Defend your home from roaming undead by setting up turrets and traps.
