Wtf...

[Sanction]

I've played every mini-game but haven't gotten the achievement for doing so...

Anyone have any ideas as to why?

There are some you have to unlock... I can't remember what I did to unlock them. If it was beating the game with every character or visiting every planet, not really sure. If you already unlocked them all, try going around again.

You have to beat a tournament with every character to unlock all of the mini games

Yeah, I did beat it (6 times I assume?). I guess I'll just play them all to make sure.

Thanks guys. :)
