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.
this is maybe a stretch but considering the way people talked about MGS4, I actually think it was an amazing game. People write it off for much the same reason that people write off Death Stranding (which is also one of my favorite games ever): because it's Kojima at his most bombastic and self-indulgent, and true as that may be, I think it also means it's the most personal game in the franchise. In making a serious attempt at writing a story about world peace, about the end of the series (which it should have been), and about his own career, he creates moments that are simultaneously absurd and heart-wrenching.
