It's very frustrating to have a looting game that has a tiny backpack, why not add backpacks as game items, that would solve the space problem... We need to use mods for basic things, so why not open it up to the community to help with the development of the game. I'm sure many would do it for free, just for the love of the game, there are even many mods with much more content and with 10x better optimization than the official one...
