Asphalt 5 worked great, however could not get Modern Combat to install, it will install in the Android Market, but when trying to download the additional files needed, I get an error saying device not supported.
While not Gameloft Games, I have also got ShadowGun, and Riptide GP running on my fire perfectly.
What I think is funn; is a game that can be bought in the Amazon App Store. Dead Space; is the one 3D game I've had the most trouble with, even though it says Kindle Fire edition. I have to open the game about 5 times everytime I want to play it; to get it to open, and sometimes it will start to open, get half way and then force close. Once it does finally open thou, it plays perfectly then.
