Merchant Caravans

I love Capitalism games but unfortunately, there aren't that many simple to use ones. While not strictly merchant games, they are of a similar vein and hopefully what you can appreciate.

Had plenty of fun with this casual game. Buy a lot, build a house, upgrade it and sell it.
Build A Lot games

Bit meatier than the others.
Capitalism 2:

Casual business builder. It's an idle capitalism game that is rather addictive to play, especially in between other things.

Sunless Sea.
Awesome adventure-exploration-survival-roguelite game with lovecraftian atmosphere that you can play as a merchant.

you should hire a skilled future king with an army to help you ;D
