By omitting Nintendo's so-called "evergreen" titles (i.e., games released before 2010), Gamasutra found that -- perhaps unsurprisingly -- Just Dance 2 was last year's top-selling 2010 release for Wii, and among six additional third-party games that made the top ten in sales for the platform. On DS, however, Nintendo games filled out half of the top ten, and Pokemon SoulSilver and HeartGold were the only titles to surpass sales of one million units each.
At first glance, PSP software sales look even bleaker, with Kingdom Hearts: Birth by Sleep on top and, according to Gamastura, the only PSP title to break 300K units sold; with the other top ten games each falling below 200K. Of course, these rankings don't include digital sales or box-copy games bundled with hardware, so it's unlikely that Birth by Sleep (which isn't available on the PlayStation Store) was the true #1 bestseller among 2010's PSP releases -- let alone the most pirated.
What is certain is that Call of Duty: Black Ops dominated torrents, as well as the games legitimately sold for PS3 and Xbox 360 in 2010. Still, both Sony and Microsoft saw two first-party releases make their console's respective top ten sales charts for the year; though each publisher's most critically-acclaimed release of 2010 -- at least, from Joystiq's perspective -- was not present. Perhaps telling of the two console's core player bases, Madden 11 beat out God of War 3 for the #2 spot on the PS3 chart, but fell to #3 beneath Halo: Reach in the Xbox 360 ranking.
Finally, we have to wonder just what were they thinking? They, of course, being all those Xbox 360 owners that purchased Fable 3 and Fallout: New Vegas instead of Mass Effect 2. Three and a half stars plus four still doesn't add up to the Game of the Year, people.
