I really like SetoKonowa's gigantic collection of games, updating constantly with interesting games.
I host a collection of games that I'd recommend to players from one of my own games, and I also host a general Recommendations collection with all kinds of story, puzzle, and otherwise interesting games. I also have two private wishlists, one for free and one for paid games. This way, I can build up a buffer of games to play, then dedicate an entire part of the day for binge-playing games with the itch desktop app.
