I love my T-Mobile G2X and its dual core gaming processor. I make sure that it was well worth every penny! So here is my personal list of my favorite android games from basic, casual time passers to hard core adventures! I will also rate them 1-10 but all of them are great games that you should try out and I have excluded many other boring ones.
