When we talk about graphic resources, we are talking about memory, a resource is stored data, severs are not supposed to render anything as they are not playing the game.

A server is in charge of processing and storing data, and hosting connections, they don't have to render graphics, a server can run out of memory, a server can experience problems due to massive data to process, or too many connections to host.

A neighborhood is like any other instance on the game, they have a small fixed amount of data, think of it like a giant instanced house in which you can't place furniture, so it takes less memory storage.

So based on this, tell me why neighborhoods are impeding the addition of more land.
