Can we get a chance to mercantilism so that it's actually a useful stat? It's really not worth investing in at all + prevents the only people that care about it (Merchant republics) from having any colonies. (I care less about this second point than the first). I feel like mercantilism should be much stronger, but in return should mean that more negative relations modifiers for trade you are stealing away from the dominant nation in the node?
I feel like merchants should also have a chance of generating a colony in uncolonised provinces within their trade range. Each merchant should have like a 1% chance of generating a colony per year with each +1 of mercantilism increasing that chance by 0.1%.
This would be historically accurate. Not all colonies were directed by government sending off happy little colonists in some massive overarching plan.
There's so much that can be done with that too; if an unexpected colony sprung up in a claimed Colonial Region, then it could trigger an event. For example, say you're playing as Genoa a trade colony spawns in Central America which is claimed by Spain.
You get a pop-up box saying "Our merchants have set up a trade colony in Belize. This region is claimed by Spain and their government is a bit miffed about it."
1) Send an envoy asking for trade concessions = +5 relations with Spain & +1 mercantilism & -10 diplomatic points & the colony stays
2) "Order our merchants to abandon the colony" = +5 relations with Spain & -mercantilism & burgher estate -10 loyalty & the colony is disbanded
Colonies spawned by merchants wouldn't cost upkeep. However, upon reaching 1,000 colonists it would cause a -30 diplomatic hit to relations with Spain as you'd promised it was only a trading post.
Something like that.
