Differences between this and Rev2?

[Stinky]

is this just less-refined rev2 or is it worth it on it's own? I own both and got this for dirt cheap on sale, but is there something I can do on sign that isn't in rev2?

You have the incredible possibility to play with less characters in differently colored stages and with some differences in movements and balancing.

And to watch an earlier part of the story.
