SCUM is pretty much the quintessential bowel movement simulator, you can always tell people are new because they'll forever be shitting their brains out.

But yeah, I think "survival" mechanics are best when they move just beyond inventory/meter management, make them actually engaging in some way, have some actual gameplay around them.

Vintage Story is another game that does some interesting things on that front, like having to bury food in a root cellar to help preserve it longer.
