Which was infinitely superior to what the modern internet has turned us into
It was different but I don't see any reason why it was particularly better. There's a reason why you can tell when something is nostalgiaslop immediately. Like if they copy those 90s black and white cool and edgy trailers, for example. In fact, if someone made a new game and had some surfer dude yell out the title of the game, you wouldn't think "This is so 90s", you would think "This guy saw this on youtube and wants to recreate it". My point being, you got mindbroken by your autism and the culture isn't to blame for that.
Also the internet has provided a sort of instant infinite mirror feedback loop that has forever poisoned creatives in a way that snail mail and magazines never could've recreated, creators were free to work in bliss of ignorance
Not at all. You make it sound like creatives nowadays are a hivemind of sorts or that they instantly respond to feedback or know what the feedback is gonna be in advance. If anything, despite the internet being bigger than ever, it has become more fragmented than ever as well, even with the 6 or so websites that are used by 90% of everyone, because those websites are very fragmented too. Indie devs clearly have different inspirations from one another, especially if they come from different countries. I can name you 10 indie games from the past 3 years that clearly have completely different lineages, and those games all have different receptions as well. You had no idea what the reaction to your thread was gonna be when you posted it, why would you think developers can tell what the average person is gonna think of their game? It's still the same process as ever. You do what you want and see how it's received.
