Still loving the game! I had an interesting thought for something that could be added as a sort of "endgame."
What if, once the country's obesity rate has passed a certain threshold (say, 90%), you could move to London itself and set up there? Maybe even interact with and/or fatten up important public figures, getting that last percentage as their state of mind changes. Not anything like "oh you become prime minister" or getting involved in the politics themselves, more just making it a location and having to fatten up those NPCs to get the "complete" obesification.
Looking forward to whatever comes next!
