My games are less "nobody liked it" and more "a lot of people have never heard of or tried it":
Ori and the Blind Forest
and
Ori and the Will of the Wisps
They're absolute masterpieces. It's like playing a video game version of a beautiful oil painting with incredibly tight movement controls. And the soundtrack.....MY GOD is it good.
It's one of those game series that I wish I could memory wipe to replay again. Sure, the story is a bit simplistic, but it hits the notes it needs to without dragging.
It's one of the best Metroidvania games ever made, but it kind of fell into obscurity similar to other masterpieces like Titanfall 2.
I played during the trial period once. I usually love games with fun gameplay loops that have a bit of grind, but I couldn't get into WoW. It just didn't feel fun. It felt like a job. I'm still not sure how it became the largest MMO ever made.
