Last month, the Japanese publisher Tecmo Koei released the Vita version of Japanese role-playing game Atelier Totori: The Adventurer of Arland. They told nobody that it was out.
In an e-mail to Kotaku at the time, one of Tecmo Koei's PR representatives joked that this was a "new tactic to get the community involved and talking about the game."
Maybe more people should try that tactic. According to today's PlayStation charts, Atelier Totori: The Adventurer of Arland was the best-selling Vita game in all of March. #1!
Of course, it probably helps that very few games actually came out for the Vita in March. #2 on the list is the Vita port of the mobile game Nun Attack. The actual sales numbers here are likely depressing.
