It doesn't matter either way because you have to be one of the top players to either be the one or in the mob, otherwise you are in the crowd and can't win anything. Plus the only time MS Points are given out are on Friday and Saturday nights in two, two hour blocks, so the chance of winning anything is very small unless you are very lucky or have no life and play the game constantly. The game is good fun just to play with friends or if you like trivia but other than that the game is not something that will win you anything of real value.
I've been playing for an hour now, still in the crowd. I hate that when I press the wrong button I can't change it.
