On a quick break right now from studying (sorry to the people who called me yesterday, I was in the office with headphones while my phone was in my room so I didn't hear it at all).
I have a proposal for a new rule that tournaments can use in the case of an interruption in the middle of a match (like a wii turning off), tell me what you guys think of it:
If a match is interrupted by an outside force that prevents the match from being continued (e.g. in the case of a Wii turning off) then the match will be restarted on the same stage with the same characters. If that match was a deciding game of the set where a win for the set could have been awarded (e.g. match 2/3 of a best of 3, etc.) then the set will be extended (e.g. best of 3 goes to best of 5, etc.). If the match was NOT a deciding game of the set (e.g. match 1 of a best of 3, etc.) then the set will NOT be extended.
I think its a pretty fair rule all around, and would work well for helping tournaments run smoother when this happens.
