I'm Worried for GMS

Not getting something is harder than you think, the way the area files interlink. It takes a lot of effort, that has to be continually reapplied with each patch, to keep data completely separate and avoid an entire tree of progression from entering our version.

If each segment of the game were actually it's own self contained module they could easily omit the ones they didn't want, but that's just not how it was designed so ala carte becomes increasingly more challenging the more content they do want.

As if every version would delete their world tour THEY WORKED HARD ON.
They would probably rather go through the pain of this.
They're a professional company.
