So Burgundy walks into Bar ... Gains a core and leaves.
*canned laughter*
I'm finding I've developed this really strange OCD thing with Europeans and the New-world. Basically I can't let any country land on it and I do almost anything I can to stop them. Usually annexing The Carnies and the like off Portugal and trying to economically cripple the "colonist" countries. It usually means I end up making a B-line straight for the new-world even if I decided I'm going to try a different goal like uniting Europe.
Not really sure why I hate other nations colonising the Americas, I guess because it usually makes them power houses and the battles tend to drag on when they have colonies everywhere. I let them have Africa though, I don't care about that one apart from the South. The majority of the provinces are too poor to even worry about colonising.
I think there's a way to stop the AI from exploring the New World in the settings or something, along the lines of "spread of coastal colonies" or something like that. I might try that when I'm doing a Europe only game or a unite the HRE map. It would be interesting to see how Europe would turn out if they didn't have the wealth pouring in from the Americas. I'm going to go with Austrians, Austrians everywhere.
