Pathfinder only, 25 point buy for attributes, no clerics or druids (play an oracle if you want that type of role), average starting gold for your class, 1 level behind the rest of the party (or level 1, whichever is higher).
Players should create a 1-3 paragraph background and post it in the character submittals thread, after which character traits will be assigned by the GM.
Rules for all of Pathfinder, with conveniently indexed links, can be found here: http://paizo.com/pathfinderRPG/prd/
