The first time I saw and played one I was a little disappointed; the ball times seemed to last too long and that giant spinning joker mechanism wasted a lot of space and missed the mark as a feature toy. I would rather it was themed based upon the comics and all that wasted space could have been the Ha Hacienda or something cool and interactive to route the ball through.
However, I played it a few times last year at a nearby bar and grill and was pleasantly surprised. The software seemed more complete and the moving crane toy was excellent. So, I think I could see myself owning this now, though it's behind Iron Man and a number of others in the pecking order. I guess in a home atmosphere, the settings and ball drains could be manipulated to make it a more difficult game.
If you're a big Batman or superhero fan, this probably wouldn't disappoint you.
