Suggestion for my land:
We should be able to buy new adjacent properties and have a bigger empire. When you buy a property adjacent to the original, its $10,000. One adjacent to one of those is $20,000. One adjacent to THOSE is $30,000. This pattern continues, adding $10,000 each additional layer. When annexing land, it would have fences next to yours, as if it was a completely new game. However, these fences will now be erasable. On the sidewalk side, it would work similarly but these sidewalks cannot be destroyed because it is the public road. If you would want to be able to connect the two sides, look at my verticality suggestion.
I am nerdy programmer that happens to like games made by ape apps. At some point in my life I am hoping to start a company and make games.
