Starfield and Baldur’s Gate 3 both weigh the player down with encumbrance. Love it or hate it, it seems like it’s here to stay.
In previous Bethesda games I eventually just started doing calculations in my head constantly about whether the stuff I was grabbing was worth the weight involved. I’m still not quite at that point for Starfield, but I’ll get there.
A UI fix to do that for you was modded in almost instantly, I’ll be installing that one tonight I think. The vanilla game is much better than I expected but I’m finding it too easy if I cheat in infinite personal storage, and too much of a cognitive burden to constantly weigh every loot item in my mind.
