I really hate to put this one out, because the first time I played I had a great time . . . but then I bought the book.
TriTac Systems did a game called Fringeworthy. It had a pretty cool concept. Sorta like Stargate* meets Aliens. The basic premise was dimensional and intergalactic travel for the elite few.
The first time we played, the GM was using a rulebook that looked like a spiral bound notebook. It was a blast.
A few years later, I saw a softboud book at my FLGS and picked it up. It was incomprehensible. Literally. Sentences didn't make sense, there was no logic, no index. The combat section was a nightmare. I was utterly bummed.
Somehow, the author had managed to take my fond memories of a good gaming experience and mangle them to the point where I could not share the game with my friends. That, to my mind, makes Fringeworthy the worst game ever.
