Beyond 22 tiles, it becomes less of a city, and more of a megalopolis, which might great for some players, but not really necessary. I used to support private boats, but now I know that the game doesn't support enough vehicles at it, even with the quadruple max.
were shortened, and even with a mod that quadruples them, I start to run out of vehicles at 22 tiles. With 9 tiles, I started running out of maximum vehicles to the point where trains/trams/etc. With 22 tiles, I run out of potential objects. Another problem is maximum vehicle numbers and maximum object numbers. There's not much point in having unlockable tiles if you can't use them all. I don't see why we have 22 unlockable tiles if only 9 can be used.
9 tiles is not enough, especially given how much space DLCs such as parks life and industries take up, however, 22 is enough.
