I've never played GURPS, nor do I want to learn a new system; but if we did D&D would we use 3.0 or 3.5 and what materials would be allowed?
GURPS is basically an open system, sort of like Linux is compared to Windows. I don't have a .pdf of the book or I'd send it to you, I paged through it at the bookstore one day and tried to find one, but couldn't.
3.5, I'd say. It's the newest, most tweaked version... that and I've memorized the Core rulebooks (Player's Handbook and DM's Guide), as well as a few other things from various expansion sources.
I suppose anything of official publishment would be fair game, and race choices would be restricted to the level modifiers. o-O At level 5 you could only go up to a +4 due to race, so we wouldn't have things like mind flayers in there... Dopplegangers, maybe, but...
