Racing sims and MS flight simulator are non-violent, but lack story. Some classic games in these categories have detailed historical settings and a lot of complexity, allowing you to create your own adventure in an open world. The adventure is different every time you play. Some classic sims of this type are here: https://github.com/sim-museum/esports-for-engineers. - Source: Hacker News / about 2 years ago

Nobody's mentioning old commercial games that were later released by their publishers as open source. One example is the classic combat flight sim "Rowan's Battle of Britain", initially released in the year 2000. You can find it packaged to run under linux/wine, along with other free games, here: https://github.com/sim-museum/esports-for-engineers the source code is here:. - Source: Hacker News / about 2 years ago

Candy Box 2 -- there is more to this than meets the eye: https://candybox2.github.io/. Source: about 1 year ago

Looking as an outsider you will see a bunch of weird-ass ASCII art that doesn't even look that good compared to, say, Candy Box, while as the actual player you're actually wrestling an eldritch beast made of deadly gas into the ground as you pulp it with a dead giant's body.

Not really like the games you mentioned but Candy Box 2, A Dark Room, and Kittens Game are some of the best browser-based idle games ever. Source: over 1 year ago

Not Candy Box or Candy Box 2, was it? Dubious guess but it does keep coming up. Source: over 1 year ago

I appreciate anyone suggesting CC Classic, but since I'd expect a JS Console minigame to be text-based, then maybe it should be more like Candybox2 (https://candybox2.github.io/ which if I'm not mistaken was part of the inspriation for CC!). Source: over 1 year ago
