I really did a search THIS TIME, before posting:
Way back in December Rockstar released GTA3 for Android. The really BIG news was that they actually optimized it for the Xperia Play. In the original press release the Xperia Play was NOT included.
Now it's not perfect AND you can not reassign the keys but it's STILL AWESOME!!! Also, version 1.0 seems to wrok the best on the Play:cool:
