The model city's will be based on the games open world for stop motion and display any word on materials or how you can destroy things ( Maybe barricade takes out a pillar on a freeway bridge

 

Lego's or model train scenery/buildings work great, you can usually get a pretty good "destruction" effect without actually destroying your scene. I know my Walmart has had tons of Call of Duty mega blocks sets on sale, I grabbed one of the Nuketown houses and it's like PERFECT scale for Evasion mode Optimus.

 

I might use train set models because I could remake all of the games levels but what can I use to make a realistic canyon with a black long road and mountains also should I make the city blocks out of wood
