[MOBILE] Android Gaming

Kirby, feel free to change to whatever fits your OCD world! There's the Mobile prefix, that would cover all mobile devices

I just bought a Nexus 7 and I'm looking for some good games. Not casual like Angry Birds, I have that shit on my iphone, but not something super intense like COD online. I was already thinking about buying Modern Combat for $7.99. I figure the single player is good enough to warrant the price. Any suggestions?
