Variety is good, but we shouldn't forget to take into account the individual qualities of each Star candidate. Two runs from the same franchise or even the same game can be starred for vastly different reasons, and putting arbitrary limits on stars per franchise or game means you'll have to make arbitrary choices between different qualities. ("Which run should we give a Star, the
100% run or the
warped run? How do we choose between this?")
Case in point, Aria of Sorrow "all souls" is currently starred because of its display of heavy luck manipulation, while "Julius all bosses" is nominated for a star because of its fast-paced action and zipping. Do we have to choose between starring a movie featuring heavy luck manipulation or starring a movie featuring fast zipping action, just because they share the same game?
Just some food for thought.
