Yea, I'd have to say that the only way you could really know if someone wins their game or not is if they prove it with a screen shot of the results. Even then, they could have played 6 games and only won one of them then post that win, and you would never know. So I think its a good concept, just there are too many variables. Only way this could really work is if you get a bunch of friends to do it locally, that way you can see first hand who wins/loses and whatnot.
well someone would have to have absoulutley no life at all to lie and make up stats every day for how ever many days and ruin the league, no one would want todo that and if someone's record was like 20-0 you could tell that they're lieing and just kick them out.
