Reading this was really insightful in the way that it put into formal, real words a lot of the ideas I was having when creating my map assignment. That generation of randomness of streets and rivers is something that I tried to simply emulate using randomness and it took me some time to realize that it isn’t enough to just create random lines starting from a center but actually have multiple points (or in the case of rivers, a line) to start paving and building the terrain.
