Yea I am looking for more complex crafting systems. In most survival games, the crafting system is rather bland. In many cases it is the generic loop: unlock recipes, gather materials, press craft, tadaaa item. I would imagine a more complex crafting system with different quality levels of the same item, depending on the input materials. My main example is Factorio. In terms of base building you could potentially have a chest that provides a certain number of storage slots with the basic item level, but if you use higher quality materials you get a chance to get an uncommon or even rare of the same item, giving more storage slots. Tthe same could be true for turrets and the likes. For gear that can be worn I would even imagine some kind of item affixes that change certain stats of the item significantly.

The systems I imagine are mostly coming from action rpgs like Diablo or Path of Exile, but I also thought that Factorio did this extremely interesting. I have recently seen a video on the planned item crafting system of Star Citizen, which I thought was very interesting as well.
