For my PCG project the narrative I have constructed is of a parent building a detailed model village for their child to play with their toys in. There is a more traditional vibe to the construction of the town with it all being laid out neatly and carefully decorated. The toys will be plush toys and will walk around the streets to locations.
The road will be generated with an L System as this provides a lot of variety once set up with the correct rules and has a lot of alterable variables to create large changes to generation. There will be a town hall, a variety of larger office buildings and a variety of houses distributed organically with randomness for variation in generation. There will be different types of trees and foliage that generate along the streets along with locations like a park.
