Simply you have to check this out!!! This is a new feature added to NHL 09 that just makes the game that much better to play. I definitely can't wait to get my hands on this.
So if you have some money to spare and want to try this new mode out, then go for it. You certainly won't regret it in the least. Just remember a common tip I heard is it is easier to make it as a goalie but don't quote me on that one.
