Got it this morning.
I played most of this morning and this afternoon, and I was mixed with sadness and overwhelming squeeness.
I love the new characters. They were created perfectly. I especially love Zero Suit Samus and Pit. (The character I'm currently obsessing over is a mixture of these two and Lucario) Then again, I'm feeling like Olimar is just a useless character that is just there for eye candy. Same with R.O.B.

I'm still up in the air with Meta Knight and King DeDeDe.
Final smashes are a sad dissapointment to me. While some characers (like Zelda and Link) have amazing smashes that pwn majorly, other characters (like Kirby and Pit) have kind of lacking smash attacks that sometimes aren't even worth going after the smash ball for.
Sadly, I am slighly dissapointed with the gameplay. It's exactly the same, with the exception of the smash ball and the assist trophies. I was hoping for something better, to be totaly honest.
That being said, I am now going to contradict myself. The characters that were from Meele (making a return) were amazingly similar, while retaining a new sense of style and gameplay. For example: Samus is slower, due to her heavy armor, Fox is faster and has speedier attacks, and Falco is slower, but with more powerful hits. Link's new boomarang was interesting, and Zelda/Shiek are the exact same, with improved graphics and control.
The graphics are nice, but the melee stages were sadly lacking. It looked like they just slapped in on from the second game. I am especially irked with Hyrule Castle's look.
The Subspace storyline is hawt! :O It makes all these funny little nintendo characters actually look half-way serious. Though I do get a little irked with the pairings here and there.
Wii controller controls are NICE. I was so glad to have such a familar feel with the controller, while making things easier to transition with (I much prefer the wii-mote to the gamecube controller).
Stage buidling is kind of a last minute tack-on to me. Really wasn't anything too spectacular, but it's still nice to have, I guess. :O
Also, being a major Fox/Falco character user, is anyone else happy with the shortened distance with their fire attack, as well as their quick attack? Now I don't see myself falling off cliffs anytime soon, thankfully.
Blah. I can't give it more than 4/5. Though is definilty a must buy.
P.S: Don't waste money on the strategy guide. It's the biggest waste of 20 bucks I have ever done in my life.
