I think Sega has been pretty good with this in recent years. SoR4 seems to be in very competent hands and Shenmue is with Yu Suzuki, so I have no reason to complain. Even the team who did the 3DS Shinobi game a while back did a good job. That said, no developers have been announced yet and until then I'm going to be a little nervous for this one too.
Honestly, I don't know.
Yeah, Shenmue 3 is being handled by Yu Suzuki himself, and thank god for that, but it wasn't Sega's initiative, they just agreed to hand over the rights.
What they actually did was to give the task of remaking the first two games to some small, unknown european indie studio (does this ring you a bell?), only to shut it off when they found out it wasn't good enough. Then they made them release an undercooked, bug-ridden hd conversion.
Problem is, this kind of approach can be extremely hit and miss.
Sonic Mania was pretty great, but of course, it was made by one the most experienced and talented fan-developer of the series.
And, ok Westone is now long gone so the Wonder Boy series might've needed outsourcing, even thought they ultimately turned it into a franco-belgian comic.
But why couldn't freaking Ancient make freaking Street of Rage 4? Why did it have to be made by some other no-name western studio that only released a decent indie beat em up?
Why couldn't Sega of Japan iself handle something so important as a Panzer Dragoon full remake?
I get that they figured out that western fans don't really give a shit about anything but brands alone, but they care so little about their identity and the integrity of their history that it hurts.
