Phoronix: Doom 3 BFG On Linux Is Still An Active Pet Project
Last week marked the one year anniversary of id Software open-sourcing their Doom 3 BFG engine changes. While they didn't release a Linux client for Doom 3: BFG Edition, a small group of open-source developers did a community Linux version via the RBDOOM-3-BFG project.
DOOM 3 BFG Edition is a remake, mostly for consoles, of a game launched back in 2004, and now the developers will make part of the engine free, for the Linux community.The last project of id Software, Rage, didn’t sold too well.
