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.

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.

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.

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

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