Um, not sure where you've been, but NO ONE PLAYS LIKE THAT. Most of the time instead of playing "first to 3 gc", we play "first to run out of unused bakugan". It's actually WAY more fun, and a bit more like the season 1 anime, and we try to be as close to that as possible.
Um... those are the rules created for playing the game. Not playing with the rules is like playing with infinity g-power bakugan.
