The Thorn Princess and the Four Knights
The players are knights who must reclaim a princess who doesn't really want to be taken home and start whining once she's been picked up by one of the knights. Fulfill the desires behind her whines, however, and you can gain her trust and convince her...
AKA: Cheaty Mages!
Players bet on monsters who are fighting in an arena. The players are also mages who can cast spells to aid or hobble various monsters as long as they don't draw the attention of the judges by casting spells of too much power.
