Sweet F.A.
I just realized something.
The main character in Metropolis Pt. 2: Scenes from a Memory by Dream Theater is named Nicolas. The main character in Operation: Mindcrime by Queensrÿche is named Nikki, which can also be spelled Nicky, an abbreviation for Nicolas. Also, one of the major characters in Metropolis Pt. 2 is a politician who turns out to be corrupt, and the main villain in Operation: Mindcrime is also a corrupt political revolution leader.
If I had a nickel for every prog metal rock opera that featured a corrupt political leader and a main character named Nicolas/Nikki, I’d have two nickels. Which isn’t a lot, but it’s weird that it’s happened twice.
