A bunch of these games people list have been released on Xbox Live, PSN, Steam, and 3DS or Switch in the past few years.
Sega's been whoring itself out to put nostalgia in front of everybody for their 60th anniversary.
This thread is almost an annual thing. Their year end shows up, they talk about how surprised or excited they are at PC ports making money or a handful of franchises in general. They talk about how they're going to invest in new and exciting things that generally don't make sense in any clear way. Blah blah blah.
Meanwhile, all the old talent is dying out or retiring. None of their IP makes big money but Sonic the Hedgehog. You need to be 25+ years old to have any meaningful, active history with Sega's platform branding. None of the Atlus stuff is above being niche, and it takes them years to release or port Persona games across multiple generations. Japan's arcade stuff never gets localized. Western PC game development houses they own are where they thrive and get no traditional "Sega" love for.
Everybody here is drinking some heavily tainted kool-aid, circle jerking about all the failures they want to see dug up and put on display.
The only quality they have left is Yakuza, and Virtua Fighter. The later, stuck in quasi-dead-franchise hell with the Ultimate Showdown/eSports Pandering Edition, being a limited, exclusive, botched, training wheels tech demo port for their team. I would jokingly say that PSO2 microtransactions keeps the lights on in their arcade centers, but they closed that shit down while re-shuffling the corporate deck for the 10000th time in the last few decades.
I want all the ports and collections. I'm also cynical, jaded, and grounded in reality enough to know that Sammy is not old Sega, and that I would laugh if Microsoft were to acquire them and actively fund old shit ports, to fill in gaps in their own lineup.
