Sorry for bringing up an old thread, but I just wanted to leave a note that triangles is only the start of boosting food. We shouldn't end at triangles, but instead work towards full patches of farms. This is because while Feudalism bonus is worded like it counts triangles, in actual fact it works like minor district adjacencies; i.e., Feudalism: Farms gain +1 food for every 2 adjacent Farms. So for example: None of the farms 1, 2, 3, 5, are in triangle formations, but they still get the +1 bonus from Feudalism because they're each adjacent to another two farms. Farm 7 is adjacent to three farms, but Feudalism only gives +1 food for every two farms, so #7 gets only +1. But the formation above is a waste because if we fill in the middle, then just as we would with districts, we get: Farm 4 is adjacent to six farms, hence it gets +3 food bonus. All in all, we're getting 36 food out of these 8 farms. If they were all just separated triangles, then we would have 2 triangles with 4x3+4x3=24 food plus 2x3=6 giving only 30 food; or we could have two sets of four-farm formations, and get 4x4+4x4=32 food. This is what happens if we take Farm #1 out: Farm 4 is now only adjacent to five farms, so it only gets +2 food adjacency bonus. So it would really be best to stop thinking about farming triangles; instead, think about farms in exactly the same way we think about district adjacencies. Obviously, when we only have space for 3 farms, putting them in a triangle maximizes the food yield by letting all three farms get their adjacency bonuses.
