Games reach Game Pass via deals similar to those offered by Epic. Microsoft pay the publisher a fixed amount, so if it is believed that it beats the proceeds from the projected sales for the given period, there's no reason not to agree to it. In other words, it's all about how much they would offer and how long it would have been since the game release.

Because I want it to be. (:

Will be getting it on Steam later on though!

It's also profitable for long-duration early access games where most of your users and potential purchasers already have already bought it. Good cash injection right at the end of development from an audience that probably wasn't going to buy it anyway.

That's just untrue. Games like Immortality, Citizen Sleeper, Unpacking, and Planet of Lana are complete, highly-rated, and on Game Pass.

Steam has a two hour refund window. Watch a stream and then set a timer and try it out.

Weird to see you getting downvoted for a legitimtate question. It's a shame Demos are not really a thing anymore.

pirate it, buy it if you pike it. dont't if you don't like it

That’s unfortunate.

Nah, it's expected. BG3 doesn't fit in a service for 7/10 games.

Any place I can try a demo?

Get it on Steam, try it for up for 2 hours, and return it if you don't like it. That's possible since years.

Pirate it. There's no DRM. Buy it if you like it.

If you or a friend has a PS5 with a PS Plus Premium subscription, you can trial the game for two hours. Your progress will transfer over if you decide to buy, but that's as close as you're going to get to a demo I think.

The only demo is on PS5 if you have a PS+ Premium. I’d suggest watching the first hour or so of a Let’s Play to see what the gameplay is like.

On steam you can try for a few hour and get a refund if you don't like it. Maybe on gog too.
