katya_stevens: Colonial Charter -- which expands the gameplay massively (and they're working on even
more stuff for it).
IAmSinistar: Wow, how cool! Thanks for that link. I keep forgetting that so many games out there have awesome mods.
Indeed :) Colonial Charter scooped up a few other mods I'd been using, and it's become pretty much my main one at the moment. I've found that some of the buildings it adds helps alleviate the end-game stagnation -- y'know, you have all the regular buildings you need, and all that's left is for your population to grow. Nope. Get some hemp or flax growing there, turn it into rope, and progress to newer buildings. Upgrade your clothier, make a whaling station.
(Okay, it probably pushes the end-game stagnation a lot further back, but there's a lot more stuff you can make, do, and grow with that mod.)
