I can create a tournament worth 1,600,000 prestige for 2 players just by making it 10,000 matches. (and the more 0's I add to number of matches the more prestige it'd be worth). And if I make it real time I believe once a person times out they are removed from the tournament so it would be incredibly easy just to break the system. Anyway, I just think there needs to be a game limit to avoid this type of abuse instead of having to go back and manually eliminate this type of tournament once it happens. I've canceled it, but you should still be able to see the prestige.

Another suggestion would be to make the prestige multiplier based on actual number of rounds not expected number of rounds...having a tournament open to 512 people in single elimination use a multiplier of 9 versus a 16 person one using a multiplier of 4 if they both end up being only 4 rounds (9-16 people) doesn't make sense. Same with Round Robins with 10 spots if only 2 get filled, the multiplier is too large.
