Yakuza producer Toshihiro Nagoshi recently conducted a lengthy interview with Edge (via ResetEra) in which he talked about the series in depth, as well as his other projects, and it turns out he'd like more players on board for the next Yakuza project.
"It will still be quite hardcore at the beginning, but I want the player to think "Oh this game seems really interesting" - that's what I'm aiming for this time. That goes for the technology too, though I don't want to say more as it will spoil the fun. By introducing new and more current systems, I'd like to increase the number of players. And if I do that, I can re-introduce Kiryu-san to some new fans. That would be ideal."
What do you want to see from future Yakuza projects?
