I hope people don't expect sequels from Panzer Dragoon, NiGHTS, Skies of Arcadia, and so on from these polls. Got to have some sort of standard with expectations, otherwise you'll just end up as a whimpering mess.
I'd say out of that list, at least keep an eye out on Yakuza, Sonic, Puyo Puyo, Football Manager, and Phantasy Star, mainly because they're still IPs SEGA uses so naturally would get attention first. Everything else be more cautious on.
(That's actually depressing...)
