Viscera Cleanup Detail is a space-janitor simulator game out on Steam right now, but a few levels taking care of gigantic mountain sized fat blobs and their slobbish messes seems like it would fit in for Weight Gaming,
Either as a mod or a standalone game, the gameplay would be essentially the same.
Small Level: The range of sizes from an extremely large roommate and cleaning up their apartment/house. Apartment would be a 1-4 room setting, (Early versions would be the 1 room,) Ideally, a bed + kitchenette at the smallest, to a multi-room bed and bath.
Houses would be two-four stories tall, basement included. You would be cleaning up around a single or two fat characters, the source of these messes.
Medium Level: Spiral Burger, a fast food chain restaurant. A feeder/feedee destination for corpulent customers. Large dining room, patio, full scale production kitchen, The place is littered with the day’s rampant feasting, fast food bags, grease spills, food stains, and other messes. Private feeding booths, and a conveyor belt of food leading out.
Large Levels: A hotel/ a mansion/ a factory built around a single or few select giant characters. Big pool for them to lounge by, a buffet nearby, and of course the trail they leave behind at their size. Messy rooms, stained carpets, shipping containers worth of food and garbage strewn about.
Extra large levels: Cleaning up after a blob this size is like maintaining a whole mountain ski-resort. A whole gondola system or train system might be needed to get around from one side of the gigantic blob’s body to the other. Giant feeding tubes that need maintaining and replacing, snow blowers to keep this giant client cool, vast storage tanks that need refilling, lakes and rivers that need diverting, canyons of cleavage that need scrubbing out, washing them. The list could go on for a while given enough time and suggestions.
Aside from the Copy+Cut for VCD, the premise is cleaning up after fat slobs/blobs
While Viscera Cleanup Detail is more curtailed towards cleaning up blood and gore, a retrenching to fit a slobbier/fat narrative on paper seems not as difficult.
The environments would be blood and goreless, unless we (The royal We) decided to do a vore level?
But, put a pin in that and leave it for later.
As for characters in the levels, the game would need a range of models. At least six, showing different sizes npcs in different states of gluttony, from thin, fat, obese, hyper obese, fat blob, and then a mountain sized blob.
Early versions would probably be devoid of the characters as the environments are built, then added in afterwards. Cleaning up after the mountain sized blob would be a level and design challenge all in of itself.
I recall a person who created 3d giant blob avatars for VR chat and roleplay, but not their online tag. This would be in that realm of large characters for this project.
What would We need to create a mod like this for VCD?
