If I were to give this game my rating. It's obviously a 100/10. One of the best video-games if not THE best video-game I ever played. Love that there are so many characters to play with and more coming in the future. The story mode is great! Sure it's not Subspace Emissary, but it's still a wonderful story mode to go through. Heck I've done it a bunch of times already. I love the Spirits mechanic as well. Online can be picky a bit. But I don't mind it. Also having all of those awesome stages from Smash's past to this game in total of 103! Now about 106, soon to be 107 when Terry is coming out. It's a lot of variety in them and I love playing the stages.
Overall...it's an amazing game.
