While Military Tactics is famously laughed at, I'd like to take some tech to poke fun of this other leaf tech. I actually didn't realize it was optional! A lot of times I feel punished when I spawn with a plantation luxury. I have to research 2 techs while every other luxury takes one and irrigation is so expensive early game. I'd rather just settle on top of the luxury if possible then build a crappy plantation over it which gives you a whopping 2 gold (4 with .... globalization!). But eventually you might run into luxuries you can't just settle over so by then I can research it when it's really cheap and then sell it to people; only to have them ask for like 1 gpt or nothing because they have it too. And this is ignoring that banana and stuff are probably better Magnus'd. You also can build the Hanging Gardens. Well, at least on paper. And you could take Oral tradition but then I just can't see keeping the jungle for long. Though come to think about it, most improvements are pretty weak too, aren't they? Except mines that get boosted multiple times and pastures?
