Really makes an arcade
The one problem I have is that there are people who play for fun and those who are so good that they hog all of the fun from even stepping up. I personally have no coordination, but can still have a great time when it is me and a friend. If it is me and another "expert", then I tend to back off or feel crappy after finishing.
The game has raised the bar for interactive gaming and I think that the move to the Playstation was a great way to bring the game to those who feel more comfortable playing on their own.
