Nintendo had a thing recently where they said some stuff to keep their investors happy. It was at this thing that they announced Wii Party and that Apple is their future enemy. They also mentioned that as of March 2010, 79 Wii games have shipped 1 million or more copies worldwide. A year earlier, that number was at 54. As you math-fans in the audience have already concluded, that means that in the past 12 months, 25 more Wii games have managed to achieve that magic, arbitrary, badge of success known as "million-sold mark".
Want to know what those 25 games are? Of course you do, but since this is the videogame industry we're talking about, we're not going to find out. I recently asked Activision to comment on VGChartz's report that Modern Warfare Reflex Edition has sold over a million copies, and they wouldn't talk. TV producers have no problem letting us know about the ratings of their shows, and film studios have no issue letting us know when their movies succeed or fail, but the game industry wont budge on questions like this. Makes you wonder why they're so paranoid and over-controlling.
When we can't get official statements, all we can do is guess. For first party games, Wii Sports Resort, New Super Mario Bros. Wii, and Wii Fit Plus are known million sellers. There's also a good chance that Punch-Out!! and Endless Ocean reached the million-mark sometime after March 2009. As for third parties, we know that Monster Hunter Tri and Just Dance have sold well over a million copies, and that's all I got for official numbers; leaving 7 down, and 18 to go. Could the previously mentioned Modern Warfare Reflex be in there? House of the Dead: Overkill? Guitar Hero 5? Your guess is as good as mine.
If you've got numbers I haven't seen, or guesses that you'd like to share, hit that comment button posthaste.
