I decided ill get done as much as i can... but probably not much but here goes my Written Concept:
The town will be about Industrial like times. Alternate world, not the same timeline as us. They are invaded by a highly advanced militaristic/Dictatorship Race. They colonize the planet, while keeping the peasants as a worker/slave race.
There will be old buildings where the citizens live. Old style... wood,bricks so on. A few factories to produce alien goods for other colonies. Military supplies. So on.
There are factories. Older style and newer style built with the assistance of alien technology. Usually older style buildings with "Upgrades" That will be visually seen.
Last section are alien structures. Military buildings. And additions will be traditional Alien style advanced bubbly shiny smooth freaky alien dictatorship of doom stuff.
I plan on it being a very dirty society. The alien stuff shiny new. Everythign else grimy, dirty, misused and mistreated.
Catch me if i'm on. Always up for a chat.
