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?
The Matrix Online. It was not a very good game mechanically, but the community and the monolith employees that would log on to role play major characters was the most fun I’ve ever had playing video games in my life.
