Which pricing game(s) do you think is (are) the most unfairly maligned? My vote for most maligned pricing game would go to On the Spot. I know the game got a lot of criticism, but I actually enjoyed it, as it had a rather unique pricing concept. Also, I don't think that its set was as hideous as many thought.
All that said, I do feel that On the Spot's set was a bit underwhelming. I think that having an elevated board that lighted up as correct selections were made (similar to what Pathfinder has) would have benefited this game. This is a bit off-topic, but I think that Let 'em Roll really benefited after its set was enlarged.
Also, I'm not sure if Split Decision is all that maligned by people on this board, but it was unfair how some thought that the game's prop frequently fell apart. As others have pointed out, that was a popular misconception, since that happened only once.
