While I agree that some games may seem like they don't "deserve it", these are all games that have captured the interest of the market and succeeded. Some you guys don't think worthy are geared at kids, and some others were cheaply made. But everything on that list is a quality game to someone.
Ever watch kids play Mario Party 8? or Karaoke to High School Musical Sing It? Trust me, they are extremely happy with the experience they get from both of those games. Smarty Pants is cheaply made and not as fun as Buzz, but on the Wii name a trivia game out from 2006 - mid 2008 that is better... Big Brain maybe to some.
Game Party, Carnival games are both junk to me, but they sold by word of mouth, so obviously there are some fans. Lots of them.
All in all, if you can capture the interest of enough people to sell a million games, you deserve it. You might not deserve my money, but you deserve the money from those who enjoy your game.
A better thread would be "How Many Wii Non Million Sellers Deserved to Sell a Million?" I think I'll make one...
