I hope the mc decides to be the king of America and gradually turn into an empire rivalling and surpassing Britain and France rather than turning America into republic and and be only a business and founding father. Maybe being a king not possible according to history but it’s fantasy anyway.
Or if you just want something to relax, you can look for an old game called Westward. It's old, but it really got me into building kingdoms and old frontier city from the ground up.
