An overview of Open Source Game Engines for Linux

There is a nice overview on Open Source game engines for Linux, which you can read on http://www.linuxlinks.com/article/20100504160447559/GameEnginesPart1.html. The overview is limited to summarizing each system, though, so don't expect in-depth comparison or advantages/disadvantages though...

While Game Engines are primarily intended for the development of games, you can use them for scientific visualization, realtime rendering or "serious games" and as such, they are potentially interesting for the architects and designers; albeit requiring development skills.

Some of them are cross-platform too, if you are not really planning to give Linux a try. I haven't tried any one of them, although I have seen the results that were achieved with Crystal Space, which was used as an engine for the Open Source "Apricot" project "Yo, Frankie" (http://www.yofrankie.org), using Blender.
