The Simpsons was one of the only shows I cared about as a kid. I loved Ghostbusters and watched it many times. I don't listen to Iron Maiden.
And yet..it's an easy decision. Iron Maiden.
(TSPP is more stop and go than I like, and feels like a lot of chopping wood. Spend most of your time going to the upper playfield. Ghostbusters is vastly improved with the new code, but it's full of cheap drains (some of which can be mitigated), doesn't have super satisfying shots, and doesn't make me want to play it over and over).
