Stratagus - GPL strategy engine

Stratagus is a GPL'ed real time strategy engine. I haven't given it a try yet, but there is a sister project called Wargus that allows you to play Warcraft II (non-Battle.net edition) on a Windows XP or Linux.

One of the games written for the engine, Magnant, looks promising.

I think the engine would have greater popularity if it were licensed under the LGPL rather than the GPL. The LGPL license would allow games written using the engine to be licensed commercially. The commercial games could donate cash or code back into the engine.

Any body want to write a strategy game with me? :)
