It would be cool if both series took place in the same universe and if Yakuza made subtle references to Shenmue. It'd be like the old days were SEGA would tie the universes of seperate games together.
Like how Space Harrier and Fantasy Zone are connected. And in After Burner 2 where you see the OutRun couple drive by when you land on a road.
heck yeah, that is exactly what I'm talking about. Not sure why people have to be so uptight about the universe thing.. it can just be kind of a low key reference to give a nod to Shenmue and please the fans.
Of course, Bayonetta references several Sega series and what do they all have to do with each other?
I still would like to see something like a mystery character for a chapter like, "a hooded master from Hong Kong" with a bunch of hints that it could be Ryo, but then kind of leave it in mystery.
Like I said, Yakuza 5 is going to need something fresh to keep the series relevant. I think a female fighter is one obvious one.
