Agreed. I’m 40 and I’ve reached a point where I feel like an adult. The biggest piece of that is that I understand that we’re all just making it up and figuring things out.
Imposter syndrome is also an intrinsic part of feeling like you aren’t an adult. Most of us experience this frequently - we have that feeling that everyone knows more than us and it makes us feel like we are fakes. But in reality, we just know more about ourselves and the gaps in our knowledge. We assume that they they know more than they do because we aren’t in their head and they aren’t expressing all the uncertainty and doubt hiding in there.
I think there is a pretty big difference between hearing people like you and me say “everyone is just making it up” and really internalizing that. I think internalization comes with time - you can believe something conceptually but often need to see it in practice over and over to really believe it in your bones.
There are other factors, too, which come with age and experience. Adults on the younger side are constantly running into new adult things and not knowing how to do those things is going to created this self doubt. “If I were an adult, I’d know how to do an insurance claim” or whatever. With further age, you will learn these things and have fewer of these doubts.
There seems to be one or two specific platformers that you loved and you using that(those) specific game(s) to state that PS2 3D platformers were generally great and universally better than today’s platformers. One does not follow the other.
And you are taking your personal preference for a very specific art style and using it as your justification for calling these platformers “objectively superior”. You keep telling people to “prove” you wrong but no matter how many specific examples people give you, you are very strongly objecting based on your subjective preferences. We cant prove you out of your own particular desire for a particular game.
