Regarding Inventory management...even with arrows (stackable to 200) I think its fun and part of a good RPG. Whats sucks is having USELESS items, or way too many types of items; which Larian excels at doing.
I really liked it in BG1 and 2 because you basically had limited SLOTS. Im a 90s teen gamer so I love my inventory slots

This forced you to think of what you need/ didn't need (though of course bags of holding negated that) And you didn't have to deal with food/barrels etc...
Then you have the <well if you feel there are too many items in the game, dont take them all!> camp. In a CRpG game? Impossible lol.
