I honestly envy people who can even be proficient at more than one character, as I only can play Ness extremely well while if I try other characters I get destroyed because of character differences clashing with my muscle memory.
I have played some other Smash games. I've played Smash 4 and Ultimate the most, some of Brawl and 64, and I haven't bothered with Melee even though it's one of my favorites to watch and learn about. I've wanted to get Melee for quite some time now but I don't want to bother spending money on an actual system or spend money on a USB-compliant Gamecube Controller for an emulator.
I heavily respect the hustle of being a Ness player, it's tough out there with so many people hating on the poor guy.
I recently watched a video on aMSa, a Yoshi player and it still baffles me how 22 years later, this game still has an active community.
I'm a cheapstake so whenever I emulate or need a controller I use a cheap Logitech USB controller(The same one that was used in the Titan submarine that went to the Titanic).
I guess I would like to play Melee too, but only for novelty purposes.
