I feel like I should have more of these than I do. I think because I trend toward playing dungeon games, often I'll take the pieces I like from a given game and fold them into my own campaigns. That said, some games that spring to mind are:

• Ryuutama. The book's production and vibes sit with me, and constantly chase the whole cozy mood the book conjures for me. Unfortunately, it's far enough from the beaten path of D&D that I'd have to either run it for my friend group or else search around online for someone to run a game, and I've done neither. In the meantime, I continue to chase its vibes.
• Mausritter. I love the set-up, which is basically "What if you were tiny and the world was a dungeon-game adventure?" I love that it's gameplay loop appears to be built around collecting resources for your adventurer's community. I love a whole lot about Mausritter, but I've never run it - there just hasn't been time in my schedule to allow me to put in the work of teaching the game to friends. In the meantime, I've experimented with using its slot-based inventory system in my ongoing Beyond the Wall game and continue to pick-up the odd game 'zine for it.
• A Rasp of Sand. I have run this one! ARoS hits on so many things I love in dungeon games - the setting's evocative, it builds in generational character play and alternate advancement, and it does a lot of the heavy lifting for the GM. The conceit of the game is your world is flooding because your village's ancestors slighted the Queen of the Sea. Each generation, a group from the village head into her randomly-generated undersea palace and attempt to return the crown stolen from her. If anyone dies in the dungeon, her anger's temporarily sated - the dungeon floods, forcing everyone out and the world stops flooding for another generation. I think about its setting and the procedural approach it takes to dungeon generation every few months.
• The Quiet Life. I am never gonna run this one. It's just too far outta my skillset and too far removed from what my players are comfortable with. But I love this game about novice nuns trying to juggle chores, strange happenings, and a vigilant pastor while also flirting like hell with each other.

And if we expand this out to video games...

• The Final Fantasy Legend/Makai Toushi SaGa. Assume that anytime I sit down to play a tabletop RPG that I am also thinking about SaGa. I've been fascinated with it since I read a walkthrough of the first part of the game in an unofficial guide I got at a school book fair. I keep trying to work the core mechanic of the Monster class - eat meat, turn into a different monster - into different campaigns. And I'm never not thinking about how God Creator can be one-hit killed by a chainsaw. Just a perfect little well of strange, evocative science fantasy!

EDIT: Looking closer at @DeusExBrockina's original post now I am out of a meeting, I realize it's meant to be stuff you obsessed over but no longer do. I kinda biffed that one, I suppose, haha!
