Super smash bros is great, but like another poster said, its not needed if you have a wii. But if you dummy have a wii, it really is a fantastic game. It's one game Nintendo rally hits out of the park. The only nit pic I have is it would be nice if your shield was weaker. But other than that is just a great game to play. My favorite fighting game ever.
Pokemon games are fun after you beat them and start really training for online. The actual games pretty much suck though. Same story as always, super easy. Basically pointless to play for the most part. But yea, if you like online battling, its fun. Takes A LOT of work, but fun.
Fire Emblem Awakening is fun. It's a bit repetitive, a bit basic, but fun.
