I think TWIZ is right on this one. There really is no iconic scenery, I don't think Colin wants to pay an artist for a theme that "resembles" zone. The Era theme is the iconic start with the van, fountain, identify house, etc. Classic's theme is the iconic start with the building, burger refugee, etc. I don't think that the zone players would even use the forum theme for Zone, if it was just benches and trees (The only iconic thing about zone)

I can see it differently if they added a dark mode with the space background, then people would use it. Besides that, no.
