The player base of PS4 and PS5 are anime fans and the shooter genre. Try selling a game like RFA or Super Mario Party on that console.
Good point and Fortune Street franchise on PS4 was simply catastrophic (under 30k).
Momotaro Dentetsu has been bigger franchise than it, but Akira Sakuma, Supervisor and copyright owner of Momotaro franchise, didin't think release for PS3 because PS3 market hadn't been good market for Momotaro Dentetsu.
