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?
Maplestory. I had a ton of fun hanging out with friends and grinding for hours with cute art. I would never recommend anyone play it, absolutely does not respect your time.
