My word is it difficult. I teied it recently, and damn, is it tough. A good portion of the cards helps the villains. Has anybody beat the Chairperson in ROok CIty on Advanced Mode yet?
I've seen The Chairman in Rook City beaten before, and I've seen heroes holding their own before finally being taken down by The Chairman Advanced in Rook City. But not that, no.
I have a hard time beating Chairperson with 4 people on an easier environment, nonetheless beating an enemy in Rook CIty. I can't imagine THAT scenario. Seems like a very "last boss" kind of thing.
Well, short story is that I'm sure it's been done. I'm fairly sure that I've never actually played that game. I'm kinda surprised at myself. I should play it when I'm not obsessed with playtesting.
I know I've done it.
I can't remember any details on it but I know the guy I was playing with would not stop until we had beaten him... it was a long night and many hero combinations were tried before success (we played 2 heroes each).
