Had an idea for a “campaign” mode, available as a DLC in which you had the option to play a military campaign, in which soldiers and guards are cheaper and equipment is purchased rather than made. An economic campaign, in which you vie to make more money than other players, or even against yourself, striving for a new record set against a time limit. Trading is easier but there is only one big deep resource. A population campaign, wherein food is easier to produce but things like clothes and shoes cannot be made. An education campaign, which would require you to build and maintain multiple libraries and at least one college or university, you would have to produce your own paper and books and be able to export same. I’m sure there could be others, add your ideas in the replies.
