ah! this can turn in an official carnival game thread.
i've played: wii sports, wii play, warioware, rayman, mario party 8, super monkey ball, rayman, big brain academy, and now carnival games.
wii sports is in a league of its own--being THE system seller of this generation, single handedly making the wii the best selling console of all time. so leaving wii sports out, here's my preference:
warioware > rayman > big brain academy >> carnival games >> wii play > super monkey ball > mp8.
if i have to give scores:
warioware 10 (even though i had more fun with warioware than wii sports)
rayman 9
big brain academy 8.5
carnival games 7.5
wii play 6
super monkey ball 7 (though i enjoyed wii play more)
mp8 5.5
actual metacritic score prediction: around 6.5, since wii sports is only 7.6
the Wii is an epidemic.
