I am sitting at 52 hours currently, and I can comfortably say that inventory management is the only thing I truly dislike about this game.
I've run into the issue where I have like a dozen half-empty treasure boxes or whatever in my inventory because they all have modifications in them, but my maxed out modification inventory is already full of much better modifications that I've been hanging on to. Why isn't there an option to trash treasure boxes?
Then, I had the issue where all of a sudden I was out of ridge-wood because I had stopped collecting ridge-wood for awhile because the icon was red, but it was red because I had depleted my ridge-wood such that I only had one inventory slot left for ridge-wood and had taken up the other 4-5 slots with some other garbage items.
I wish I could dump anything I thought I might need later into a chest or something. My hoarding is now to my detriment.
It's a small complaint in the grand scheme of things, but I was in the middle of the last Cauldron last night when I ran out of ridge-wood. I made it out with like 3 hard point arrows and a tearblast arrow left.
