Like the thread title says, what are some of the most obscure games that you've played and absolutely love?
One of mine has got to be Typing of the Dead for Dreamcast. It became an instant hit at game nights back in the day.
A Dreamcast backpack and keyboards strapped on their waists.... Genius!!
Edit: When I say obscure, I mean barely known of, odd, strange, hard to understand or just weird games.
