It's not just NIS america. Xseed has the rights to 5 trails games and some of the earlier YS games as well. Ultimately it's too risky financially to release these games since historically JRPGS don't sell well on xbox. Also consider the new xbox consoles install base is around 28 million which sounds like a lot but is acutally pretty horrible for consoles. That's roughly half of the last xbox in the same amount of time. Xbox as a console is a dying brand. I don't blame Falcom, NIS and Xseed for ignoring it. You except them to spend the money and port over 20 games to the xbox? Not worth it. The market isn't there to justify it. Anyone serious about JRPGs already has a PlayStation and/or Switch or even PC.
