I don't hate Smash, but I'm not blind to the fact that out of the 5 million sales it got, maybe 100,000 of those bought it because of the gameplay, and 4.9 bought it because of the characters.
In every game, and in every sport, skill is not determined by knowing when to do something. It's a combination of knowing when to do it plus the ability to actually DO IT. If skill was only based on knowing when to do something, every armchair quarterback could win the superbowl, but because skill is a combination of both knowledge and execution, not everybody can get to the superbowl.
This is no different in anything that has any element of competitiveness to it, such as fighting games, RTS and FPS games. In fact, I'm going to show you an example of it from my own personal match in Virtua Fighter

That combo in the last round there is a ring-out combo on that character, but hitting that combo required four things: knowing that my opponent was going to step back slightly at the beginning of the round, knowing my opponent's character is of a certain weight class that's light enough for that combo to carry (Virtua Fighter characters have different weights), the ABILITY to actually hit the combo perfectly (up until that match, I had never performed that combo correctly in an actual match), and knowing my opponent wouldn't make it out of the ring so I had to add that final kick to push him out.
There are four aspects to hitting that combo, but if I didn't have the execution and ability to actually perform it, all the knowledge in the world is fucking irrelevant. But that is why competitive games are the way they are, to separate the ones who want to win and the ones who just want to play.
