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?
X-Com: The Bureau Declassified. Your “teammates” are fundamentally suicidal, making keeping them alive almost impossible. But the setting, story and challenge made up for it. It was inventive.
The Technomancer: Mid-budget game by Spiders. Was short and straightforward, which most people disliked, but I thought it was a blast. The story still sticks in my head screaming for me to write a novel based on it.
