I actually have been obsessed with all of the super smash games since I was tiny ~.~
N64: Awesomeness for it's time
melee: I was amazed when this was released, I use to be able to kick major ass with pikachu, but since so much time has passed I have started failing at melee

I didn't like the cheap tricks a lot more advanced players would do (like spiking a person right off the edge like a volleyball with fox...works even if you have 0 HP ;_;)
Brawl: I was very disappointed when this released, however I learned that most of the characters have a different feel in this version than melee. And for some weird reason I am a lot better in brawl...( I barely play it o.o )
IMO I like Brawl and melee both in their owns ways and when I play with people I be sure to have both games with us! XD
