I'm fairly critical, so there's not too many on my list, but the biggest one is that I liked Quest 64 (somehow) when I was younger.

I also love La Mulana 1&2, along with Deadly Premonition, though those are more "cult hits" aka critical failures that 'widely disliked'. But, I'd definitely hesitate to recommend any of them to someone unless I thought they'd be into it.
