Re: GM wanted for my first game
Pathfinder is generaly considered, I believe, to be "DnD 375" or "DnD 3.5-and-a-bit". I seem to recall that some people got the DnD 3.5 rules and tweaked them and stuff, simplifying some stuff that was needlessly complicated and stuff like that, but they weren't allowed to actually call it "DnD" for copyright reasons so they just called it Pathfinder instead :). I've not used it myself so far but I've played some 3.5 and loads of 4th Edition.
