This may or may not be new footage of the Ichiban Kasuga Yakuza game
Reporting anything on/around April Fool's is a nightmare, tbqh.
Yakuza series general director Toshihiro Nagoshi has confirmed the next Yakuza game will star Yakuza Online's Ichiban Kasuga and this video may, or may not, be our first peek at it.
The reason I'm hesitant about the news is that it's April Fool's day right now in Japan, and this video appears to suggest the game has command-based RPG battles in it.
However, the video comes via the official YouTube account for Ryu Ga Gotoku Studio, and we do know a new Ichiban Kasuga Yakuza game is in development. As spotted by Gematsu, the video - simply entitled "ryu_new_0401" - appears to show "stolen" footage of the new Yakuza game. Here, take a peek:
We had an inkling a new Ichiban Kasuga Yakuza game was coming to PlayStation 4 when Sega announced it was auditioning actresses to portray Kasuga's new partner but not much else was known until Nagoshi confirmed the news at Sega Fes 2019.
As Gematsu points out, though, Yakuza series general director Toshihiro Nagoshi said only this weekend he would "like to change the [the next Yakuza game] drastically"... and command-based RPG battles would certainly be a change.
Given the date there's a chance any or all of this might be rubbish, of course, and if so, it's a fantastically elaborate joke. I'm more inclined to believe the mode will feature as some kind of mini-game, though, but who knows? Reporting anything on/around April Fool's is a nightmare, to be honest with you.
