Example; the Legend of Zelda: BotW and TotK weapon degradation system. At first I was annoyed at it, but once I stopped caring about my “favorite weapon” I really started to enjoy the system. I think it lends really well to the sandbox nature of the game and it itches that resourcefulness nature inside me.
The lack of interpersonal conflict in Star Treks overseen by Gene Roddenberry is a good thing. Humanity got their shit together, made Earth paradise, and went exploring the galaxy and other frontiers in life. Shoehorning conflict and darkness into the newer series destroys what made it unique.
I couldn’t quite pinpoint what I didn’t like about the newer series, but you’ve nailed it - the hyper realistic tone it now has really clashes with the explorative nature of the old series.
