I just can't wait to make the most evil (but beatable) stages anyone has ever seen!!
The stage editor alone has already confirmed my purchase, but with the ability to use parts from characters and robotmasters to make custom megamen is just the icing on the cake!
Not to mention MM2 is my favorite in the series (I know it is a bit over hyped, but there is a reason) and to have a remake with all this just makes it that much more special.
Also Inafune commented awhile ago stating that he would like to re-do the entire series, I think he is going to do it all in one game-Megaman Universe.
Just imagine every new add-on to the game will be the stages, characters, and powers for the next installment. I think I may be more excited for this game then ANY other game in my entire history. I grew up starting with the very first MM game and now my dreams of creating my own are slowly coming true.
