Funny you should bring this up Telegraph because between me and two of my closest friends we have every newest generation system and we even have Brawl that we could play on the Wii but whenever we get together we always break out the good old N64 and play Smash Bros for hours haha. That game is awesome and although the character choices aren't as vast as Melee or Brawl and the graphics are ages behind their successors it is just reminiscent for us whenever we get together to play it over and over again haha. I mained Pikachu in the first Brawl and always used to piss off my buddies because of how fast Pikachu can grab, plus he can edge guard like nobodies business with his spark and thunder and quick attack is a life saver sometimes. But to put them in order I would say Smash, Melee, then Brawl.
