A great example is "A dark room". Another example (although it's a bit too complex for what I'm researching) would be Dwarf fortress.
Any other intriguing games that you can share?
Also, if you were to build such a game from scratch, what languages/platforms would you use? e.g. "A dark room" is open source and uses mostly Javascript [0].
Thanks for any suggestion!
