There is nothing that strikes me as overly excessive about my inventory. I have too much coal, tin and copper at around 200 each. I built a second blacksmith forge to turn that into saleable bronze gear. I have around 200 each of wood and stone, which I do not consider excessive, as I can burn through that much in minutes if I go on a building spree. I’d need a lot more than that if I build city walls. If I’d known about this item limit, I likely would never have built 140 picket fences. I am using the jewellery mod which has added ~300 items from gems and the like I’ve accumulated. I’ve got around 300 food items total, but the game actively rewards you for accumulating food (and deployed items), so it never occurred to me that it would then return later to slap you down for it.
From those things mentioned, that’s ~2000 items tight there. Then there are lamps, windows, chairs, beds, tables, etc., etc., plus weapons, tools, and all manner of sundry. There are no excessive numbers, just what I would think would be normal. I ditched a bunch of things like superfluous furniture and the like to get about 400 spaces of grace, but I don’t think it would take much to fill that. If my people collect the stuff they’ve already gotten from mining basic rock, they’ll fill that.
Anyway, I do understand that the game has this limit because of performance issues. The point of my post was that such items should not pose any performance issues at all! The fact that they do means that the developers have done something seriously weird, something unnecessary, that has resulted in an extremely inconvenient cap on the game’s potential. Items in storage should be nothing more than number data sitting in memory, it should involve absolutely zero processing.
