Its Smash Bros. If you have a 3DS this is one of those required games haha. Casual or competitive, this game rocks all the boats, capsizes them then jumps to a new one and repeats it. I'm pretty casual and I main MegaMan, Palutena, Pit/Dark Pit, various Mii Fighters, Shulk, and Mario. I enjoy making Mii fighters the most and using the Customs as well. Creating fighters in fighting games is always a very fun and varied thing to do.
