Can you say that the guy correcting Nacierman has the title of the pitch wrong and is trying to correct someone with false information?
Twilight of the Gods was an opera that gave the inspiration for the title Moore actually used. Twilight of the Superheroes was the title of Moore's pitch.
I seem to remember it being referred to as just "Twilight" when I first heard about it, but that was ages ago.
Anyway, Moore's story was the first thing that came to mind when I first read what Bleeding Cool wrote about it. Let's face it, DC/Johns has made it a cottage industry mining Moore's stuff in the past few years.
