SSB. The first SSB. You know, on the N64? That, to me, is the best one.
It didn't have wave dashing, it didn't have trophies, it didn't even have final smashes. It had 9 stages (up to 12 or 13, if you counted stages that only appeared in 1P Mode), 12 characters, and a handful of items.
I'm not saying Melee or Brawl were/are bad, I'm just saying that maybe we don't need all these bells and whistles that the two sequels come with. Who has time to collect 290 trophies or 350 songs anyway?
