What's a game you love but have NEVER heard anyone mention anywhere unless you looked it up?

And I mean never. Not rarely mentioned, but never. So much so that it made you doubt that it even existed and was just a construct of your mind. For me it's always been Severance: Blade of Darkness. What a brutal game. It's so dark and was ahead of its time. It's even ahead of most modern games in some aspects, since it allows you to mutilate your enemies' limbs and decapitate them in combat. Not as a finishing move, just randomly. It mildly traumatized me a sa kid because of its music and atmosphere, and that's the definition of an epic game. So many different weapons too. What's a game that fits this description for you?
