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.
It’s not quite ye-olde-tyme, but Delver is one I’ve put a hundred or so hours in. I played it a bunch because it was one of a handful of games in my library that would run on a chroot on my old second-hand student chromebook back when that was all I had for a year or so. It’s real time and 3d but low-spec pixel with an appreciable art style, and plays as you would expect from a true roguelike. Good sound and music direction. Difficulty is pretty well balanced, in my opinion, erring on the side of a bit too easy especially with as much time in it as I have. Shame the game didn’t get as much attention as the studio was apparently hoping for, as they’ve basically abandoned the property. There’s some small activity on the workshop, but I rarely mess with mods.
