As with most Mario sports games...this game rocks out loud in multiplayer. 8)
My favorite characters from the game: Hammer Bros., Shy Guy, Yoshi, and Mario.
I'll lend in my ratings:
1-Player Gameplay: 9/10
2-Player Gameplay: 10/10
Life Span: 8/10
I'm starting Mario-videogame reviews in the Mario Mafia topic; feel free to make some reviews there too, Sneaky_Sneasel.
