Short answer: Yes.
Long answer (also sorta an excuse to have the characters xd): Many people have done it before for videos, and as long as it’s not the ENTIRE game, it should be fine.
I have decided yesterday that i would make half of one of my games by creating the landscapes and placing houses,trees and roads. My first game is a simulator called Falcon Blox, and only my avatar should be used as the main character while the rest is vehicle based.
It’s basically a Roblox version of Falcon BMS, feel free to look at the Falcon BMS information and tell me what you think of it.
Thanks for giving me a great reply and a good solution.
