This is me, playing Teammate Madness (or Team Building depending on which country you live in) against three CPU Mii's on Master Difficulty.
I think the problem with this one (and the majority of TV Party games) is it has too much of a luckbased playing field. No matter how good I am at the minigames, I tend to end up with a crappy pool of Mii's to choose from. And if there is a pool of Mii's that can get the maximum points, I always end up playing minigames that give you nexttono chance of winning (Sitting Pretty being the worstcase scenario).
Had no real problems with this game though, but this whole luckbased playing field thing really annoys me.
