Excluding all games you have seen mentioned by anyone on the internet, what is your favorite game?

So if I'm not counting close friends recommending games to me as "mentioned on the internet" probably Crystal Project, according to Steam. Otherwise, we'd need to go back to things that I was told about by family members way back in the day that I both like and haven't seen mentioned online since, which is trickier. Thief The Dark Project, possibly?

If you haven't played Thief: The Dark Project I recommend it and its sequels. Don't play Thief (no subtitle) though, it's AAA garbage.
