I try to download 3-4 new games a week. I haven't really found one that grabbed me in the past 3 months.
Rayman Jungle Run (when it was free) and Angry Birds Star Wars II was a nice distraction for a few hours, but not anything I would say is a must play.
If you're a more old school action-oriented type of person, two of my fave games currently are League of Evil and Danmaku Death (Android). Looking for similar games if anyone knows of any.
