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.
I bought a physical copy for PC cheap on sale, and never played it (my PC at the time wouldn't run it for some reason IDR).
Now I live in Japan and it's not available for sale here, on GOG or Steam, so I hope I can get that disc to work under Linux! I see there's an official patch that removes the DRM, but there's one for North America, and another for Europe, and I bought the game in Australia, so I it's a coin flip which one I've got. Hopefully once I install it there'll be some clues.
