I feel like JP devs are being too reliant on Game Pass, instead of actually trying to cultivate an audience on Xbox a lot just want a check upfront. Game Pass should be a way to familiarize people to ur franchise and then naturally support the platform. I think Yakuza is a good example of this. It's just unrealistic to expect MS to drop a deal on every and any small-mid size JP game, I honestly think this is why we aren't seeing the smaller SE titles on the platform.
edit: Btw I meant Yakuza being a good example of how to use Game Pass to build an audience, and then support xbox without GP.
