It was great but didn't surprise me.
If you pass up all the repetitive music and the special effects lacking the word "special" then I would have to mention how the battles didn't surprise me. The best thing about Super Smash Bros. is that you take these people from completely different World and make them battle(Mario vs. Pikachu, Peach vs. Link, Sheik vs. Donkey Kong, etc) but these battle were all together. It would been nice to see some variety with such a nice choice of characters. Tails vs. Megaman, Kirby vs. Chrono, Shadow vs. Gohan, etc.
Need not worry though, I still love it and I hope to see some more great flashes from this collaboration.
