Unreal Engine is the world’s most open and advanced real-time 3D creation platform for photoreal visuals and immersive experiences. Good stable game engine alternatives to Unity3d and Unreal Engine4? Unity and UE4 I hear are more 'experimental' on linux. The websites still advertise for Mac/PC only. Is there a game engine(s) on Linux that is stable and capable of commercial/ indie games? Atomic Game Engine. Here's a nice list of Engines that support Linux in some.

This is a custom engine to use with the data files from either retail versions of Duke Nukem 3D Atomic Edition, Mac or PC. It is for PPC Mac OS X only.

If you don't have a retail disc, the installer can also install the shareware data files, which leaves you with only episode one, and various other shareware nagging.

It works on my computer running Mac OS X 10.4.11 or Mac OS X 10.5.8.
