High-profile publishers tend to kick off massive marketing campaigns for their titles years before said titles hit store shelves (did you guys see that trailer for Halo 6 yet?), but preemptive advertising is rarely the strong suit of independent publishers. Speaking at GDC, Sony development relations manager Chris Eden warned self-publishers of downloadable titles about the perils of poor marketing, saying promotion-shy developers often send their brainchildren "out to die lonely and unloved."
Eden suggested that PSN developers take advantage of the official PlayStation Blog and Playstation.com to spread the word about their projects. Of course, success in this venture would require having a title worth talking about, and not a Q*Bert clone with updated visuals and a new protagonist who possesses overwhelming levels of 'tude.
