I always wait for release, even if I’m planning it to be a release day buy. Early Access could be an exception if the product they offer is good even in that stage, like how I got Rhythm Doctor when they finished Act 4. (The game has recently came out of Early Access and it’s really good). A demo could incentivise me to preorder, a game I could give example for that is Diesel Knights.

Strictly against it in AAA titles, anything above 60 is a never buy in the first place for me but a putting a preorder for a game in that price range is something that is straight up NOT happening under any circumstance.
