If your a collector pick this one up
Basically this is just the vs. game included in mario 3 for nes where you have the POW block in the middle, so if you have that then technically you dont need this game but if you like to collect games then this is a definite must. It's definitely fun to play now and then and it can only go up in value so you might as well get it while you can before it becomes too rare and expensive!
