How come the postal series isn’t allowed on Xbox ?

There is no ban, and there's a remake of postal 2 coming

Hello and thanks for getting in touch. I'm Aileen, and I'm here to provide you advice as an Independent Advisor.

You're not alone in thinking the Postal series would be an interesting fit for Xbox. The games definitely have a niche following, and seeing them on Nintendo platforms has surprised a lot of people—especially considering how restrictive Nintendo used to be with mature titles.

That said, bringing Postal to Xbox would depend entirely on the developer (Running With Scissors) deciding to port it and Microsoft approving it for the Xbox Store. Some factors that might affect that:

Content policies: Xbox has content guidelines, especially around violence and offensive material. If the game pushes past certain limits, it could get flagged or rejected.

Developer interest: The devs would need to invest time in optimizing and submitting the game for Xbox certification.

Community demand: The more fans speak up and show interest (like you're doing now), the more likely developers are to make the move.

If you’re really hoping to see Postal on Xbox, I recommend reaching out directly to Running With Scissors on their official channels or social media. They’ve been known to respond to fans and are pretty transparent about where they want their games to go.

Please let me know if you need any further assistance. Looking forward to your response.

I’ve set them all to stereo uncompressed, sound still isn’t coming through. What else can I even do? And how come my mic works but sound isn’t.

this time finally i checked everything as stated this problem never arrived earlier how come suddenly this error arrives and means that billing address does not match with credit card payers address or so or any thing related to postal code ,and when i
am about to renew my xbox live membership that time everything is correct and postal code billing address matches automatically is there any explanation or else i am wasting my time

I can see your intentions, and they are good but a thread of people moaning about a postal issue wont allow you to prevent it happening again
