I did a search and didn't see a thread on it. I recently bought the game, haven't played much of it but so far I like it. I got MegaMan Starforce 3 Black Ace. I got some questions.

Is there any big major differences with the other one I forget the name but I know it has Red in it. Or is it basically the same as Black Ace with very very little differences? I do know it says if you have both version you can connect both to unlock MegaMans true form. If anyone has both, is it really worth getting both?
