just occured to me what this seeded problem is..
what they should of done is an unseeded list of 64 players.they probally would of but couldnt find enough rubbish players to put on it.problem with wipeout is nearly everyone is fantastic at playing.chances are that those who are not will be as they really only have to be good on there 3 tracks and the default one to beat their opponent.
in theory if you were good enough you could say to your opponent "hey look we will just assume you won all your races so lets just do mine and then win the default race.shame i would never be in a position to do so but im sure there are a few who could comfortably do this.
