I know this game ws not built for multi story buildings, but i would love to see a system that creating multi-level is there. Possible having to create scaffolding around the building in order to create levels. Having the scaffolding be different material and be made out of certain materials also possbile hard to walk on. Creating a bit of realish to the game and make the building of cities better. If house building and public buildings we a bit easier i think it would make new players have more of a interest in the game. Also having cities look amazing as many already do. The time it takes to make a building would be signifitly decreased. For now once a multi-level building is built, it will most likely never be redone. I look forward for having a bigger population. With that having a better building system would much improve the game and attract more people.
