I'd been looking forward to this game for ages and it doesn't disappoint. There's the main boardgame, a one player challenge game which isn't particularly taxing to complete and a load of extras. The best thing is the huge amount of minigames which all use the wiimote very well, looks like there are:
27 Duel 18 4 Player 10 2 vs 2 9 1 vs 3 5 Battle 3 Challenge
The perfect game to get a few mates round, have a few beers and laugh at games such as Tightrope walking, lasso-ing, 2 player boat rowing & spinning giant eyeballs (needs to be seen to be believed!) to name but a few. I can't believe who dreams this stuff up, but it's genius!
Only nag is that for some reason gameplay on mine is in 4-3 aspect rather than all the start and menus which appear in 16-9 on my widescreen telly. Checked all the settings are widescreen so not sure why this is the case.
