I've been to the Manitou Springs arcade. Here is what I remember:

Great variety of pins from all eras. They had a LOTRO there and it didnt play well. They also had a DE Star Wars that sounded like it was talking underwater with a pound of marbles in it's mouth. It is also spread out across like 5 different buildings and you can't see it from the street. Not pinball related... We did the Molly mine tour in Cripple Creek. That was amazing. The mining museum across fromt he USAF Academy was so-so still neat for the kids though.
