Sega said a year or two again that they wanted to focus more on multiplatform. This means that some IPs that in the past were exclusive no longer will be exclusive.We’ll have to wait to see what happens with Persona 6. Yakuza like a Dragon was a pretty popular
Still whatever anyone thinks of Yakuza or Persona, or the smaller niche titles, PS had a small percentage of fans loving those games. Now Yakuza is more popular than ever, alot of games are blowing up in popularity compared to what they use to be. GOW, Horizon, Uncharted, Ghost of Tsushima etc.
It has nothing to do with MS or Sony deals, means that Sega wants to make more money and doesn't need moneyhat.
PS players had Yakuza and Persona, have Yakuza and Persona and will continue having them. But maybe not exclusive. In any case, maybe sometimes some timed exclusive, some marketing deal or something like that. And same goes with the other platform holders.
And yes, Yakuza and Persona have their fans but compared to GoW, Horizon, Uncharted, TLOU, Spider-Man, Gran Turismo or Ghost of Tsushima they are smaller niche games.
