We are in the realm of opinion, so I want to offer a contrasting one. We had a great time with it, and yes, it was a one-off thing. The scenarios are about $15 a pop which compared to taking the same group of friends to a movie is a bargain. (and MUCH more engaging, imo) It is like a multi-player point and click adventure with light roleplaying elements. I don't know if it should have won the SDJ, but then again, it didn't. :)

I don't think movies are good benchmark. You go to movies relatively rarely and basically because someone I group really want to see the movie or to be able to talk around watercooler if movie is really popular.
Most people dont go for movies outside those constraints if ever. Movie is rather expensive choice people normally don't do.
