So I went to gamestop today to ask about tournament specifics. They know almost nothing about the tournament. No idea which characters will be unlocked, no idea what stages will be allowed, what items, etc, but I'm assuming it'll be only the starting roster (at least at my GS) with items.
Our tournament will be starting at 10 PM on March 8th. They're taking sign ups before the tournament even begins, not 30 minutes in advance like the website said they were. When I asked them about it, they didn't even have a list going, so they made one on the spot and I was the first name on the list. I doubt my gamestop will have many participants because of the fact that the tournament isn't really advertised much so most people don't even know about it unless they happen to go to the GS website. Hopefully they'll start advertising it locally sometime soon. Either way though, it's a win-win for me. If a lot of people sign up, it'll be more fun, but if only a few participate, I have a good chance of winning.
Since the tournament starts at 10 PM, I'm assuming they'll have the wii set up ahead of time and will allow people to play a bit before it starts. Might be a good idea to go and check to see if you can get some practice matches in if you haven't played Brawl yet.
Oh, and from the rumors that have been floating around, the winner of the first place tournament supposedly gets a free copy of Brawl.
