I usually prefer to let the storehouse and granary to manage it, cause sometimes I find that there isn't enough resources being transferred to the trade center because they're too busy with their stalls.
Whatever you have the most of! Make selling goods from your rich deposits a priority right from the start, and you'll be a thousand-aire in no time😂. FYI you don't need to purchase a trade route for any goods that are not considered a "major trade"
This game has a massive learning curve. I can’t remember the last time I had to watch tutorial videos for a game but here I am, and it’s well worth it, because I’m completely broke lol. Thanks for the video
