What's your favorite game that you can't really recommend to people?

Maybe it's too niche. Too difficult. Too weird. Or maybe it's just bad but there's something you love about it anyway.

I feel this way about Deadly Premonition. I know in a lot of ways it's just not a good game, but I feel like it's particular brand of weirdness and storytelling speaks to me specifically so I love it anyway, but I struggle to recommend it to other people.
