Hi everyone I haven't had Ubuntu for long but I feel it has more potential for game development than Windows 8(DON'T USE IT, IT BLOWS!). On Windows I used XNA, but I wanted to have a development Environment on Ubuntu since I'm not sure how to access art and music files from Windows. So what frameworks(Engines preferably) can I use for Ubuntu game development?
You probably want take a look to answers on question What 2D/3D engines and game SDKs are available?
I would recommend choice framework based on programming language which you are familiar. If you previously programming with XNA maybe MonoGame is something what you want check out.
Games can be created also using Qt framework. Not sure how good this framework is for games, but It's one of the best UI framework so knowledge of this framework would be useful anyway.
