The Surprise Contender

While known for scantily clad volleyball, the DOAX series features a deep, hidden weight system. Each girl has a hidden "BMI" stat that changes based on what you feed her at the hotel restaurant. Feed a character high-calorie Italian food and ice cream for a week, skip volleyball matches, and she’ll visibly plump up—thicker thighs, a softer midsection, and a rounder face. Conversely, salad and constant swimming makes her lean.

Why it’s cult-classic: The game never tells you this outright. Discovering that your favorite character has gained 10 pounds from your vacation menu is a shockingly detailed simulation.

Platform: PC (Flash/HTML5, on Newgrounds, Itch.io)
The Unapologetic Indie

If you want a game about weight gain, not just featuring it, the indie scene delivers. Weight Gain Adventure (by Studio Kumiho) is a 2D RPG where the main character’s weight is her primary combat stat. Eating food in dungeons makes her stronger, unlocks new abilities, and changes her sprite dramatically. The plot revolves around a kingdom where "fullness is power."

Similarly, Feeder Simulator on Itch.io and The Griffin’s Saddlebag mod for Skyrim transform mainstream games into full-blown expansion fantasies.

While text-adventures might seem dated, FTAT is widely considered the cornerstone of the genre. It bridges the gap between pure imagination and visual feedback.

The Simulation Father’s Dilemma

In this classic raising sim, you play as a father guiding a young girl to adulthood. What you feed her matters. A diet of steak, cake, and fried food leads to the "Plump" body type. Certain endings (like "Gourmet Queen" or "Barmaid") actually require high weight and low exercise stats. It’s a delicate balance—too much gain without strength can hurt her career options, but the game unapologetically includes size as a core stat. best weight gain games
