I am looking for world type ideas here. What type of world is Blade Runner for example? Worlds names like dystopian world or cyber punk world.
The world of Blade Runner is an alternative present. After all, the events of the movie, made in 1982, took place in the far future time of 2019.
This would be the present except our present has a suspicious lack of aerocars, replicant androids, and colonies on other planets. Even the architecture and cityscapes aren't the same.
A present time that isn't our present time, so it's an alternative present.
