I love hearing about unique takes on game mechanics. Someone recently convinced me that limited inventories are kind of abused currently and that unlimited inventory systems would give more player choices.
Having well placed saved points and QOL features is absolutely amazing. I'm not interested in spending 10-15m running back / repeating myself just because the save progression system is rubbish. A lot more developers are more respectful of your time in that regard so it's a great improvement
I feel save points themselves are becoming an increasingly archaic design choice. Just let us save anywhere, especially in a single player game. I think most people are just suspending games without expressly saving most of the time.
