Cafu Engine

Hello. I'm the project leader for a free (of cost), high-quality first person shooter (check the link in my signature) named Project Blizzard, and I was wondering if the license allowed for freeware, freely distributed games, and if this was covered under the term "commercial use".

If your game is free, Ca3DE is free. See

http://www.ca3d-engine.de/phpBB2/viewforum.php?f=10
for more information.
You will have to work with the publicly and freely available Ca3DE-MDK (New Materials Development Kit); that means no access to the full source code. That is normally not a problem, though: The MDK is very powerful and probably more than enough to complete your task. You'll also get support here.

That means I can't try to use the GNU license, since I don't have all the code used for the game, but that sounds...phenominal! But, I don't even understand engines much (this isn't really my best subject); what programming language is needed to write a game using the Ca3DE-MDK?

C++, requiring the OpenWatcom compiler on the Win32 platform and g++ on Linux.
Some introduction and details are given in the NewMaterials.pdf document which is contained in the Ca3DE-MDK or available (latest revision) here: http://www.Ca3D-Engine.de/e107_files/do ... erials.pdf

Btw, I don't think that the GNU license prevents you from using closed-source binaries in your source code, but I'm not legally versed either.

Thanks. But, this either means spending a long, long time learning C++, or scrapping the lead programmer. Decisions, decisions. Still, it all sounds great.
