I'm about to have a weird little nostalgia story time, so be warned:
I never really go into a Smash speculation cycle with a specific character or characters in mind, I'm basically happy no matter what because when I first played the original game I didn't really know any of the characters, aside from Mario, Luigi, Pikachu, and Jigglypuff, (for the longest time I thought Link's name was "Lee" because the announcer didn't fully pronounce the n and k at the end), so it was really the game and the gameplay that I fell in love with and then I eventually learned more and more about the characters and their games.
Then Melee came out and suddenly there were more characters that I know and more characters I know nothing about
(To the point where I ran into some serious confusion because of a walkthrough I read online that some of the unlockable characters were Gandalf (meaning Ganondorf), Captain Falcon's sidekick Falco, and Mr. Game & Watch who was the man that lived in the basement of the drug store on the Onett stage. Then Brawl speculation started and when I saw Snake my first thought was "third parties can happen now? I want Sonic" then I got Sonic. And ever since then I've had characters that I would like, but they were never make or break for me. I got Rosalina, Lucina, Palutena, Duck Hunt, and Ridley, I got Mewtwo, Snake, Squirtle, Young Link, and Wolf back. Then the impossible happened, I got Banjo-Kazooie.
Basically, what I'm getting at is that I'm basically happy no matter what, if I get Shantae or Agumon or Spyro or the extra impossible (Glover or Bonk) I'll be ecstatic, but I'm perfectly content either way.
This became a weird stream of consciousness, so... Sorry if I wasted your time haha.
