I'm building a media centre and am wondering what my alternatives are for a main application. I've looked at XBMC, Miro, BOXEE, etc... and the one thing that seems to be lacking is support for gaming. I could just install PlayOnLinux and/or DJL and use the media player for movies/tv and the other for games, however it would be much nicer to have "a single interface for it all(TM)". Does anyone know of one flexible enough to do this without being a full-blown DE (and thus remote-unfriendly + confusing)?
