So has anyone ever written down the maths to prove that the Longhouse is actually inferior to the Workshop? Given the +1 goes to the base production and is then multiplied by the other % modifiers it seems to me like the longhouse could actually be better in some circumstances, if not all. I might have to have a look once I get deeper into this game. I figure that even without the food benefit of working lumber mills instead of mines, the longhouse might not actually be terrible. Hypothetical (pretty simple) example - 15 citizen, 6 working lumber mills, 7 working riverside farms and 2 working uni specialists. +5 base production would give what? 18 production? from the six lumber mills, equivalent to 6 mines but with +6 food over the mining scenario, essentially moving the balance of production to food focused citizens. In the scenario of a vanilla civ with a normal workshop, you would have to only work 5 mines to keep nearly the same growth (8*4=32 food vs 7*4+6=34 from iriquois). Assuming 5 keeps the same # of turns to pop growth, you get 15 base production vs 18. Note that the workshop only gives a 10% modifier to boost that to 16.5 v 18. This proves the advantage of the longhouse in an over-simplified and early situation. I'll obviously have to look at the yields a bit throughout the game and compare relative yields at different times to prove whether or not the longhouse is better overall. As a quick analysis, it comes down to whether +base hammers x other % modifiers works > +10% base hammers. I guess the other point to mention is that it synergizes well with the free forest roads of Hiawatha too. Looks like I'll be playing either a science victory or modern domination I guess. I could try for cultural, but I have no idea what I'm doing there... we'll see!
