For Wihelmina, I don't really know what are the options. How to make her ability interesting and not too powerful while the whole civilization is already powerful.
I believe the Trade Route have to be interesting for both ends. Why would I want to send a Trade Route to the Netherlands for them to enjoy a free Culture? Except for the Agenda, there is no point. Maybe her ability should be unrestricted. For example: "
Each internationnal Trade Route from or toward a Dutch city yields 1 Culture and 1 Loyalty for both cities."
It will not be strong, but at least it is useable. You could also add a little extra but gimmicky thing with the Broadcast Center since the ability's name is "Radio Oranje". For example: "
Each internationnal Trade Route from or toward a Dutch city yields 1 Culture and 1 Loyalty for both cities. Those values are doubled if the city has a Broadcast Center."
When I look at England or Spain, I find it quite weird to have some of the bonuses of their unique infrastructure are spread within the civilization's abilities. Why the free naval unit or the Strategic Ressource stockpilesnot part of the Royal Navy Dockyard's bonuses, but from Victoria's and England's abilities instead? Why the Loyalty bonus not part of the Mission's bonuses, but from Spain's ability instead?
For England, putting some Victoria's ability into the Royal Navy Dockyard would make Eleanor enjoys them. But is this really a problem?
I wonder if they are going to stick with the clunky continental system with those both civilizations, and if they are going to stick the colonisation gameplay. England seems to want to settle unclaimed land on foreign continent for additionnal Gold and Trade Route, meanwhile Spain seems to conqueer foreign civilizations for... winning the game and better Mission? Yeah, it is not very clear.
Either they abolish this continental non-sense, or fully embrace it. Right now, why as England and Spain would you want to settle anything else than foreign cities? Would it make better sense to have different gameplay but equally interesting if you are on your home continent or foreign one? So you are not getting frustated to not fully enjoy the bonus if you happens to not be able to settle foreign lands? Like this:
- England: Cities on your home continent would have more Production with a Naval focus, while cities on foreign continent would have more Gold with a Military focus.
- Spain: Cities on your home continent would be more secular with Mission yielding more Science, while cities on foreign continent would be more religious with Mission yielding more Faith (and maybe Tourism at Flight?).
Here the ideas written. This is just a draft: I have no idea if this makes sense or if it is balanced or not. It is just here to picture it more easily:
