I'm an hour behind so pretty much in the same situation. I'd last til around 4am. Anyway, assuming that you know what Pokemon is, there is a TableTop Adventures homebrew based around it. Files are here; <a href="http://www.mediafire.com/?c5cpr5p5z3ybca3" rel="nofollow">http://www.mediafire.com/?c5cpr5p5z3ybca3</a> (fair warning, it's chunky as hell). But I'd run just a small campaign using that. My Thing campaign is based upon John Carpenter's Thing from Another World remake's expanded universe. I'll also assume you've watched the scariest movie there is and know what The Thing is. There IS a Thing D20 system, but mainly for beginners I simply ask that you decide on a number of roles, get given stats and make up your own characters as you try and discover if The Thing is finally dead in an Argentine rainforest.
