Throwing this around as an idea. There is some complaints that coastal cities don't hold up as strongly as more land based ones...especially island type cities. One change that may assist with that, and give imperialism a boost as well. Take the +1 production for coast, ocean, and lakes from the finisher and put it on Colonialism. Then move the 25% upgrade reduction to the finisher (the finisher would still include the science bonus). Or swap the science part of it instead, whichever makes more sense. I think this moves gives island heavy players an option to strengthen their cities more as well as reinforcing imperialism's sea based theme. And no big code changes for G Thoughts?
