My major gripe with fo4 was always that you had to micromanage your inventory, and it was mentally taxing to me to have to constantly bring my inventory under the limit. I pretty much gave up on the game for the past 5 years, and just recently tried the game again, this time with mods. The game is super fun now! Why game devs implement inventory management, I don't know. May be it's fun for everybody else, but I absolutely hate it.
