I've always thought that to come up with a good idea, you have to go through a lot of bad ones. I use RPG Maker, and I remember that one of the worst ideas I ever had was a character in a creepy scene who only appeared when you weren't looking at him. It seemed like a good idea in my head, but in practice, it was awful.
If you go down that path, I imagine your game will be something like the movie “Plan 9 from Outer Space.” That movie became a cult classic because of its technical flaws, so if you know how to make the most of it, your game could become a cult classic too.
