So instead of Sonic Team + Sega, now we have Yakuza team + Sega.
Heh, I know I'm exagerating and Sega always had/has more teams, but the way you wrote that down was funny to me. And makes sense, Yakuza is hard on it's way to surpass Sonic as Sega's flagship franchise.
I don't know if I prefer Japanese Sonic Team or American Sonic Team. The Japanese take more chances, are more shameless and enegertic and tend to create the most memorable and fun parts of the franchise, but they're unreliable and tend to fly off the rails pretty bad.
The Americans are more reliable and tend to give people more what they want, but play it too save and tend to be a bit bland as a result.
Plus are wayyyy too Meta these days. So I don't know.
Eh, I can forgive them not resolving Sonic Generations ending, that was clear to be a comedic punchline at the end. And it's difficult to write a resolution of that in the next game without it feeling clunky. Lost world's story would feel awkward if it has to start with Eggman escaping limbo first when it has nothing to do with Lost world's events.
If anything, I'm more bothered with how the plot of his games are pinballing around with several plotpoints having either no set up or pay off during the adventure.
But I ranted enough about that, so never mind.
That said, no idea if Morio Kishimoto is to blame for the story lines.
At this point I'm weary of pointing fingers at any individual, to me it seems the whole development envirement around Sonic is a giant mess and there's no one villain to blame or one hero that'll resolve it.
