I got this and No More Heroes on Friday and gotta say they're the first AAA non ported exclusive 3rd party titles i've played for the Wii.
Absolutley amazing and with a couple of releases down the line this will be a perfect gameplay experience. I finished work on Friday and went to the pub with all of my work colleagues so this game was sat on the table and I got about 15 people asked me about this game and all said they had a Wii (who knew) and were wanting this game if I said it was good.
The terms Spread, wild fire and word of mouth spring to mind here for this game.
