Oof, I have a huge boner for roguelikes, and most of them are open source. My biggest time sink is still Dungeon Crawl Stone Soup, playable online at https://crawl.develz.org/

What about games inside of games? I remember hunkering down in some random medibay in System Shock 2 to play some OverWorld Zero on my GamePig.

Hotline Miami - When I need to work out like hell. Stardew valley - When I feel like chilling out. HOMM III - When I pretend I’m on am epic quest while commuting.

I was one of the original refugees from digg.com. This feels like R*ddit of old - simple layout, techie userbase, friendly community. Feels like home.
