Gamasutra wasn't able to get its hands on year-to-date PSN sales data directly from Sony, but it has come up with some interesting conclusions based on an unscientific look at ... leaderboard stats. The site broke down January's new releases, as well as a few other games that sold well last month, and the big debut of the month appears to be Hustle Kings, which added over 39,000 players to its ranks. Assault Heroes only picked up 754 new players, but given that it's a game that actually came out in 2006 on the Xbox, that's not a big surprise. PSN also offered up its "10 for '10" sale in January, and Uno came away from that event with a whopping 87,000 new players on its leaderboards. Braid and Critter Crunch also did well, adding 20,000 and 17,000 new players to their leaderboards, respectively.
Keep in mind that these numbers are far from official, and not complete anyway -- Vandal Hearts: Flames of Judgment, Thexder Neo and Matt Hazard were released on PSN last month, and none of those games are included in this analysis, due to unreliable or nonexistent leaderboards. But it is probably fair to say that PSN had a pretty good month in January, especially with the games featured in its "10 for '10" sale. More of that, please.
