Some good ideas... thanks for the tips. So how can/do you consistently get lots of CG? I think of one of my European allies sold me a few. Other than that no idea how to get more.
You rarely get a lot of them tbh, that's why I prefer to specialise them. I think the most I've ever had is six, when my colonies were on a peninsula right at the north so I had no shared borders or wars with other Europeans, and used trade to get open borders with all of them.
In my last WOI I never lost a city at all, considering my coastal cities were my main cities. Perhaps a better idea is have your main cities inland? And perhaps it's ok to let the REF take coastal cities so they'll move inland towards your inland cities and navigate through large areas of forests? I wonder if that will work?
What difficulty do you play? Have never encountered a feasible scenario in Revolutionary where you can hold all coastal colonies against the massive waves of RLI and all their naval bombardments. Although I generally never try to defend the coastal colonies due to the +50% bonus RLI get when attacking them.
I usually have at least some of main military production colonies inland - the ones which produce food, horses, blades and guns. That way I can always win the WoI without risk as I can defend them against any REF incursions.
One last question: I've always repelled REF waves each time. Do they actually go after your inland cities if your coastal cities are still there?
They always have for me, at least I assume that's what they are doing when they move out. They definitely don't just sit in the coastal cities, though they may be moving out to attack others.
