Rogue likes usually run on a toaster. What’re people’s favorites?
I have a huge soft spot for Crawl: Stone Soup. Runs in a browser, or probably even lower requirements if you download it. The game’s design goals want to minimize tedium and gotchas, so it’s pretty respectful of your time. Auto-explore and auto-travel are real nice. So is the global search for when you’re like “is there anything in this run with resist poison?”
I’ve played a little nethack, adom, and angband, but I always go back to crawl.
My favourite old timey roguelike was:
The Dungeon of Doom shareware version, 1987.

Mainly because it was the one available at the time.

Favourite current roguelike is Shattered PD with 5 challenges added.
