Androrc the Orc
Emperor
I understand the problem about the Bandeirantes, as they represented mostly Sao Paulo rather then Brasil, but I find them really interesting and were a huge part of Colonial Age. I read somewhere about a bonus for converting a barb camp unit into a worker, and while that is quite representative, I find it lackluster at that part of the game.
Yes, the idea for the plantation UB would be quite good. Pumping that up with the Pantheon +1 culture from plantations and you've got yourself a strong empire. What do you think would be fitting? The Latifundio? I can't recall anything right now... I once though of the Casas de Fundição, as during the late colonial age, Portugal implemented those houses to make sure people would pay the taxes correctly. Could give a gold boost to mines, as it was really associated with the mines of Minas Gerais. Also, it could replace the mint, giving +1 gold from mines, but wouldn't it be kinda overpowered?
Well, we're getting somewhere. Nice to see a brazilian fella here!
Latifundio wouldn't be a good idea as a UB, I think, since they weren't located in cities, but rather spread throughout the land, so they would be better represented as a Unique Improvement. The Casa de Fundição, on the other hand, would work really well as a UB.
