What do you mean by old school rules? Which version of D&D?
I'm interested, but if you pick something simpler than oldschool D&D I can bring in two friends of mine who're rather new to roleplaying but very eager to try.
4E D&D or New World of Darkness come to mind. I like the idea of NWoD crossed with Serenity. I don't care for Joss Whedon, but I do like the setting.
