It has the best graphics I've seen on the Cube so far. The sound suits the game very well, although I don't know if it's just me but I feel the voices on some characters could be improved. Seems like they just got some members of the team to supply and it shows.
I've played it for about 12 hours so far and am probably less than half way through it.
I'm giving the game an 8/10 though. While it's fun to play, we've seen it all before and some of the sub-games are annoying.
