A reader has pointed out that the Savage 2 FAQ addresses the possibility of a Linux port:
Let me start by saying that I would like to do a Linux port. However our new engine (name K2) is DirectX driven, but we are contemplating doing an OpenGL version for a Linux port. Its not ruled out by any means. We’ll definitely contact those guys (transgaming.com) and do what we can to make sure it emulates as well as possible, port or not.
This is similar to the situation with Neverwinter Nights 2, where a Linux game’s sequel utilizes Direct3D, complicating a potential port.
Savage is a RTS/FPS multiplayer hybrid game developed and ported to Linux by S2Games.
