Other than the gameloft games, there are not many high quality 3D games on android.... yet. But you'll see more coming now that we have some crazy hardware.
ID Software is hiring android developers. Most are guessing that they are going to port Rage to Android (already being made for iOS). It looks CRAZY.
The Unreal Engine is also rumored to be coming to android. It's the same engine used to create the Epic Citadel tech demo on iOS. I had a change to play around with that and was blooooooooooown away.
Hang in there. The games are coming
