Numen: Contest of Heroes is a game that sits at about 50% recommended on steam. I beat it years ago and really enjoyed myself, but I knew it was a unique fit for me. I only say “bad” so that we have common ground, but I value that experience.
What are “bad” games you enjoy?
Something key to remember is that when a game gets “Mixed” on Steam, eg 50/50, that still means half the people who play it enjoyed it. Half is not nothing.
For instance, Aliens: Colonial Marines. To my knowledge, AI was kinda shit, but could be fixed in a text file, but apparently a lot of people still enjoyed it otherwise.
So there’s probably a lot of these that have niche appeal to people.
