For me it's Archer for sure. It was the most brilliant brutally funny show I've seen in years and I would love to have that as a pinball machine.
As for Iron Maiden: Their music is something very particular that might not call out to a broad audience. And even if Maiden were my favorite band, I would not buy a pin of them, because as always with music pins: If I play it too often the music starts annoying me. That's fine for a game on location but it would kill any band for me on a home setup. And I would not want that to happen to my favorite band.
