a game revolving around multiplayer fun, this game must be played with friends to get a 8 or higher in reality.
The story brings every big Nintendo character together in one story. it's pretty huge, and i had a fun time playing it.
there's a lot of things to do if you can only play alone. there's tons of things to try and get, like trophies, stickers, but mainly trophies. they come from completing challenges, and locating secret areas in the story mode.
All in all, this is a very good game. Nintendo definitely had a EUREKA! and created this game.
my advice? this is a must buy, and it's replay-ability is pretty swell. but it's much more worth it for playing with friends. :)
