It had nothing to do with NISA that was all Falcom's doing. Nobody on the switch or PC bought their games in quantities to justify porting.That's because NISA is an asstacular company that doesn't know what it's doing. In most cases, the PC version would be better. It's still true they trickled out platforms for that game to tard cum their speds. Bandai is doing that a lot now on Switch. They're announcing ports months after a game's initial release in the hopes that spergs buy again for portability.
the PS4 got a version of Cold Steel 1 and 2 with even more enhancements than the PC version and also got all the DLC for free. The DLC for the PS4 version will also instantly level you to level 250 or something insane so you can start on Nightmare mode. You also have all the costumes and everything else on the disc itself.
3 and 4 are not coming to PC due to Xseed biting it and NISA taking over. Since Falcom isn't going to dish out the money for ports, that fell on NISA and they're not going to spend the cash to localize it either, since again the other platforms didn't buy shit in actual quantities.
Basically any sort of major weeb support on other platforms is a fiction, much like The Grinch leak or Persona 5 being ported to Switch. The Bigfoot Truthers have a better track record at this point.
