Story Creation contest = each team is given a set of very random maps and odd characters, and have to make the most interesting story out of it possible.
Eventing contest = Each team is given one small map (size limit, not the map itself), and a limited number of characters and must create the most interesting situation and creative eventing to win.
Mapping contest = Each team must make one full town from RTP, with houses, interesting NPCs and some special event happening, such as a town meeting, parade, etc... Best town set up wins.
Boss Battle contest = Each team must make a final boss style encounter... including the event where they confront him, and events during and after the battle for added effect.
Dialog contest = Each team is given a DIFFERENT set of completely odd characters (stuff like a man in love with a chicken, etc) and told to make a good dialog between them as they were just meeting for the first time. Best done dialog wins (funniest, most believable, whatever)
