If they could do that it would be similar to the fair on the docks of GTA V by the beach but it would move which I am not sure how they would pull that off seeing as you don't need to sleep. So unless you have to leave the area for it to move, it would get messy .
Yeah I think the two games play quite differently even if Far Cry 5 does come along with a Western Theme. I'd really still just prefer a Blood Dragon 2 myself only because it was so over the top and awesome at the same time.
