Iron Maiden is pretty solid in my opinion. Played about 100 credits on it so far. Scoring is fairly easy to understand. I did notice that it is sensitive to set up. I played about 20 different ones at Midwest Gaming Classic and some felt like crap while others felt great. The Loop Jackpot shot is hard to hit more than twice. The playfield multipliers aren't mystifying either and you can elect when to turn them on which is nice. I have no doubts it will be regarded as a classic. It was designed by Keith Elwin who I consider the best player in the world (doesn't matter what rankings say). He made it as a homebrew with an Archer theme, but then Stern hired him. I like it way more than Star Wars. Guardians of the Galaxy is growing on me. Played one in a tournament this weekend really blew it up. Batman 66 I've played about 5 times, so I don't have an opinion on it yet.
