Each group will have one player nominated by the DM to be awarded MVP. DMs set their own criteria, but we look for players who are fair, self-sacrificing, kind, helpful, funny, and cinematic.
The Prize: The player with the most votes wins a $50 cash prize (via PayPal). DMs are awarded ½ point for every slot they run to qualify towards the goal if they play at least one game. Ties are decided by a d20 roll-off.
