One thing I’ve found that helps is not watching trailers and reading articles/threads. I’ll watch a single trailer, usually the first one and then ignore everything else. Now I get to discover everything on my own and don’t have a ton of preconceived notions and opinions already in my brain when I first boot it up.
It’s made my gaming experience a hell of a lot more enjoyable again
If it’s an unknown studio or something I’m dubious about I like to check spoiler free reviews after the launch just to see if everyone hates it/it’s broken or not and then I’ll give it a try. Other than that I still try to avoid most media about it. Reviews, trailers and forums give so much info, spoilers and wish lists presented as fact that it can lead to let down I wouldn’t have had otherwise
I’ve also tried to let go of the idea of what I want the game to be and just let it be what it is, which for me has made them much more enjoyable
