I got all the way through to the end of the first world before I realised what a mistake I'd made buying it. The graphics are okay, but the music was nice at first but would probably drive you crazy. The thing that messed up everything though was the sensitivity. I'm sure that SEGA had it in our best interests to make the controls super sensitive so that even at the SLIGHTEST movement, it would move. Now that works fine on SP but on party mode? It's downright impossible. It's impossible to do anything in darts, it's impossible to steer in racing because even if the wiimote is straight, your player still turns. Pretty much everything else is probably the same. Had SEGA made the controls more responsive and less sensitive, this may have been an incredible game.
Unfortunately, it's anything but. Sorry SEGA, but I want a refund. Either that or I'm selling it to a friend.
