Viral marketing drives videogame sales

My friends at eRoi did a good job for Konami to promote their first videogame for Sony PSP. The Death Jr. advergame generated over than 1.5 million unique visitors in its first month online, getting traffic most of all through word-of-mouth (65% of which were via influencer and peer-level word-of-mouth, according to eROI tracking statistics).

A month-and-a-half after hitting shelves, Death Jr. sales are exceeding projections by 135%.
