Sega highlighted the performance of Persona 4: Golden, in particular, a PlayStation Vita game from 2012 that launched on Steam in June this year. Sales of the PC port were "significantly higher than expected," the company said, and that has influenced its strategy going forward.

"Going forward, we intend to aggressively promote the porting of previously launched titles to Steam and other new platforms," Sega said.

"Under such direction, we would like to take multi-platform rollout in account and prepare the PC version and others from the start."
