My ideal wg game would probably be a mix between RPG, dating sim, and life sim, kinda like the three modern Persona games. One big thing for me is having the option to pick the protagonist’s sex before starting. I’m more of the opinion that the weight gain aspects of a game like this should be more present in the simulation parts of the game than the RPG sections. It would be fairly slow, gradual weight gain. I also wouldn’t want the weight gain to forced on the player, just heavily encouraged by
short term convenience, but at the “cost” of longer term consequences. There would be a heavy focus on things like inner monologue from the protagonists perspective and unique dialogue from NPC based on things like the character’s current weight level, eating habits (if the NPC in question would be aware of that), and how quickly your character is gaining weight. As for the RPG portion, I’d leave the weight gain affects to be simple, but noticeable. I’m mostly referring to simple things like stat changes, lower speed and/or agility, higher defense etc. Having armors be restricted by the character’s weight level could be kind of fun if there was also an option to adapt said armors to different body sizes. I haven’t quite thought of a general plot, but I would prefer a modern day setting due to the higher amount activities related to weight gain that would be available to the player. I would probably have the weight level be capped at just before immobility, and reserve immobility for premature endings to the game (the endings would be difficult enough that they would only be able to be achieved if the player was trying to get them). The early endings would have multiple variants based on story progress and relations to a handful of NPCs. Resource management would be a major mechanic as well. The player would be managing things like money, food, time, weight level, clothing that fits the player, favors from friendly NPCs etc. Companions would have their own lives outside the player by having variables to keep track of how they live their lives. Things like, how much income they receive, their dietary habits, weight level, and general happiness. Companions would also be able to gain weight by subtly influencing them when the player decides to hang out with them. An obvious example would be taking them out to restaurants repeatedly would cause them to gain weight. A less obvious one would be if the player allows the companion to pay for you too often, it would lower that companion’s personal wealth to a point where junky fast food becomes all they can reasonably afford, causing them to gain weight over time. I would prefer the game to be fairly long, around the 60-70 hour mark.
I might have some good new for you. Forgive me for self advertising a bit here, but I’m making a weight gain mod for a medieval strategy game with RPG elements called “Crusader Kings 2”. The base game actually went free to play a few months back, which is all that’s needed for my mod to work. About the game itself, it is a unique kind of strategy game because unlike most other games in the genre where you would play as a nation, you instead play as a character that is part of a dynasty that are in charge of the nations on the map. This game has a weight gain and loss system that was added last year. The system was extremely basic though, so I decided to overhaul it with a mod. Main features of the mod are:
- I’m making the process of gaining weight more interesting by adding popup events once the player reaches certain weight thresholds.
- Added a fetish system by using character traits. The traits are “fat fetish” (This one fills a double role as fat admirer and a feeder) and “feedee fetish”.
- changed the way the weight gain system works by making it more gradual, and based off of character traits rather than being more pop up event oriented.
- Adding more ways to interact with the other characters. Example: Taking a spouse out on a dinner date, causing both characters to gain weight as well as raising the characters’ opinion of each other.
- A diet, metabolism (based on the character’s age and sex) and physical activity system to more directly influence the weight gain/loss.
- Fantasy elements that will able to be toggled on or off based on player preferences (I still need to do this). An example of this would be the selection of weight gain oriented potion system. I also have integration with a popular, albeit risque, fantasy mod for the game called “Luxuria Fantasia”, but it’s not required.
To get more specifics, I’ve been posting about the mod’s progress a lot here: Crusader Kings 2 - 3.0's weight gain - #341 by failmuseum if what I’ve said sounds interesting. Sorry for the massive post.
