You can create yourself a nice round protagonist in the character creator. And thanks to the modding community, you can take it a lot further.

Go diving, go exploring, eat the freshest sushi. Dave the diver is lovely.

Furry fat fetish destructive golf game. Sadly I only heard of this game today because its developer passed away.

Men who are chubby star in this game, based on the developer's manga series. Doesn't look like a great game, but it's so rare to see chubby (and also disability rep) in a Japanese game.

Point and click adventure, 90s style. Parody of Batman, where he's an unemployed junk-food addicted slob. Pretty obscure puzzles - feels more "click on everything" than "figure it out".

Teddy (Forrest Kaysen), what a man. Ask him about food.

Puzzle game where you play as an ever-dancing portly Death. Lovely little game, if you enjoy puzzles. A demo is available too.

Nope nope nope nope. That's my first reaction. But that might just be because I think of Santa as being everyone's parents so it triggers my inner incest nope.

This is actually a survival horror game. But you do play as a fat dude.

This is one heck of a weird game. It's like a whole range of old-school arcade style games, built into one. But the running theme is - you're a pig, you need to eat the things, you get fat, you vomit.
