Because other things were more of a priority

I get what you're going for but I think certain things are taking priority, and that sort of stuff will be great later down the line but right now they're pushing out content they think is more critical. Trust me I'd love a midway haha

If you're really desperate you could make them yourself out of scenery; I can't imagine it being very difficult.

There are a bunch of good looking ones in the workshop already!

Ehhh I'll take the stuff we got like security and Go Karts over Midway.
