Had an idea last night while I was having a celebratory cigar. It’d be awesome to introduce tobacco as a crop into the game.
Not only would you introduce the crop but you can also add several production buildings similar to brewing. In order to obtain cigars you’d first need a drying barn for your tobacco as in early colonial times in the Americas.
Lastly, once the dried tobacco has been produced, you transfer it over to a cigar rolling building to roll the cigars. Perhaps not only would cigars make your people happy but also sell for a good price with traders.
I’m sure there are many crop ideas in this game, but this was one idea I had that would require several post growing processing buildings.
