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.
Shadow the Hedgehog isn't a masterpiece by any means, but aside from a couple of obnoxious missions, I found it blandly enjoyable at worst. The story is actually kind of adorable in its tryhard edginess, and the soundtrack has some legitimate bangers.
I like how you can shoot NATO Troops (or their Sanicverse equivilent at least) and Sonic gets mad at you
I have a fondness for tryhard edginess. Idk I grew up on Jak 2 and 3. I can never explain why I find it charming.
I liked it as a kid, then I didn't like it for a while, but in recent years I've come back around to liking it again. I guess it reminds me of being a teenager so it's a bit nostalgic - but also I think part of why I've come to appreciate it is because modern pop culture is annoyingly self aware ("well that just happened" laugh track) so I appreciate media that takes itself seriously even if it's going over the top.
I absolutely loved Shadow the Hedgehog. For a while it was probably the most replayable game I had, I probably played it 100 times +
