I honestly think that everyone who I play against will be horrified at how bad I actually am. I am seriously a terrible gamer. That said, I will never tire of being pwned, so you can always count me in for a game.
We still don't know how this online thing will work, anyway. We'll most likely register usernames, but seeing as the survey at nintendo.com asked about a few other options, there's always the possibility that we won't. I highly, highly doubt it though.
If there are names, I'll most likely go with -KN-, since that's what I use on MSN. But I could also be KnowsNothing, Root Beer-kun, KnowsBeerFun, or Socks Blvd. When I create my videogame production empire, the studio that started it all will be called Socks Blvd. So watch out.
