Technopoly has an interesting idea - building around structures on an island, improving resource production until you have enough to build bridges to different islands, rinse and repeat, with a fine art style and some interesting flavor. Sadly, you need to pay real money or watch ads to do pretty much everything. The most egregious offender is about the bridges you build between islands, which get doled out at a glacial pace if you don’t want to pay premium currencies. That’s all.
