Today I gave DccNiTghtmare a try. I learned about the project on the LGT.
DccNiTghtmare (aka DNT) is a project to make a Free (as in free speech) 3D single player RPG in a sarcastic post-apocalyptical world. Any suggestions are welcome, just put them at our forum.
How convenient! I'm a big fan of apocalyptic settings, single-player games, sarcasm, free software and projects that encourage participation!
First impressions after starting: Weird music, strange resolutions limitation, interesting races (Headbanger, Strange Autistic, Mutant Human Cricket, Human Llama).
The controls are contumacious and the graphics engine is either slow or unstable (it either crashes or slows down to unplayable speed when I exit the first area.) This means that I can't say much about playability. The clown care seems right though. So if you're into bizarre humor, you should get DNT, just to be able to read the race/class descriptions.
DNT is a project by DNTeam, "a group of developers and artists involved on creating free (as in libre, livre) games projects." Another game they're working on is XUT, a Button football game. It looks like fun, but there is no release yet. Unfortunately it is under "not so active development."
