Topic: What should I spend my Microsoft Rewards points on?

Hi all. First ever post on here, so please be gentle with me.

I've got some microsoft points saved up and there is currently a sale on the Xbox/Microsoft cards. A whole 5% here in the UK, which is better than nothing I suppose.

Here's my nice-to-have problem: I can't think what to spend my points on. Normally I'd blow them on an upcoming game, but I can't think of any in the next 90 days that are Xbox exclusive. I also have a PS5 and tend to buy any cross-platform games on that, purely because I like the haptic triggers. I so wish Microsoft would do an Xbox controller with haptic triggers, but that's for another discussion.

I also have Game Pass Ultimate, so don't need to buy any games that come with that.

So please could you give me some advice on what to spend my points on. Or indeed whether I should save them for something in the future. I understand that any redeemed points have to be used within 90 days.
Ideally I'm looking for something Xbox or Microsoft specific. Something that I cannot get elsewhere. That way I feel like I've got the most value out of my points.
It doesn't have to be software. Any hardware tips would also be appreciated.

Thanking you in advance and wishing you all the best.

According to the following on the FAQ:

Your Microsoft Rewards points will expire if there are no earning or redemption activities within 18 months.

In theory, you can save your points for Grand Theft Auto 6.
