Well most of the games can be found on some kind of Nintendo site... very few are actually on the Wii site, strangely... but you can check them out:
Nintendo.com: Wii featuring Bust-A-Move Bash!, Cooking Mama: Cook Off
Don't got to game-reviewer sites...
...they're... er... kinda' unfriendly to the Wii.
I mean come on, most Nintendo fans disagree with gaming reviews. Trust me, the bad ratings on Touch Detective for the DS??? People who've actually played the game the whole way through thought it was REALLY fun!
In my opinion, I think it could've been a classic if enough people actually played it (Nintendo fans are fewer in number than people think)... *sigh*
