Since we're talking about not being good enough to play melee competitively, I again have to bring up TowerFall: Ascension. It's mechanically and game theoretically similar enough to smash that smash players generally like it (though obviously the good ones consider it less of a 'real' game). At a high level, both are by and large about free-form movement and character control more than anything else; finding a positional advantage and an opening to punish your opponent.
Much like Smash in the early days, people are generally fooled into believing it's just a fun party game. For reference,
see here although you should basically ignore the commentary as it's largely impossible to commentate on a game where matches last 10 seconds.
tl;dr melee is probably a better game, but mere mortals can actually learn to play TowerFall at a high level (just hyper-jumps) without destroying their wrists doing all the cool shit (wavedashLcancelDIwhateverthefuckelse)
