I liked this article I founs on OSNews.
http://gamesuy.blogspot.com/2007/12/top-10-free-linux-3d-games.htmlThere are nice 3D games and some are open source. It will be nice to have some ported to OS/2-eCS, but possible we will have some issues on the 3D part with the video drivers. But it is fun to read.
