G.E.C.K released for Fallout 3

"Earlier today, Bethesda Softworks released the Garden of Eden Creation Kit, Fallout 3's official editor. As with every other big-name title that has mod creation tools, I fully expect to see you guys come up with all sorts of crazy, disturbing, and even hilarious quests while I sit on my ass and mash on this keyboard."
