(Epic) Android Games: Recommend your favorites!

Hey Army,

I just finished a few games that I had bought on sale, looking for something new. I'm sure I'm not the only person looking for some good suggestions!

RULES:

Game Title, Brief review, rating out of 10 (if you need criteria, think quality, quantity/price, enjoyment)

-Only ONE game per original post.

-No posting "endless" games, ie. jetpack joyride, etc.

-Suggest games that have a clear beginning and actual ending, such as something with a final mission, last challenge. (ie. Nova3, N4Speed Most Wanted).

-Preferably games that do not require in-app purchases.
