Superbot would have to update the customize and character menu through patches, but what if the made a $5 bundle with new supers (1, 2, and 3) for EVERY character? I think that this would be a great addition to the game seeing that it would cause a bit of unpredictability in online play. It would really test opponents in online play and would be fun for someone who has mastered a character. I wouldn't add this too soon though, seeing that some people are still getting used to the gamely...Opinions or ideas for other supers?
While it is a good idea, what people fail to realize is that this is also a fighting game, and introducing an element that's ingame that you have to pay for is generally a very, very bad idea.
