A fair number of other popular games have holiday versions of their maps that become available during the holidays. I think the community would enjoy it if beamng got into that trend, and spiced up the maps to fit the holiday. Pumpkins, ghosts and other Halloween decor on the maps during October, and around Christmas time there could be Christmas lights hanging everywhere, Christmas trees, presents, etc. Just a thought.
I could see that working, as a Prefab (Similar to scenarios) with the objects added. They would only be enabled at certain times of year. For example, the game would load the Christmas objects in if the map is selected and it's that time of year.
