Which is why they're intimidating to new players.
Not really. They look cool. That's about all they need to do.
Honestly, every video in Smash that has crazy stuff going on(which is in every game so far bar none) is just as intimidating. It has nothing to do with Melee. It's the fact crazy stuff goes on without explanation. Explain the stuff, and the problem disappears.
Every single game is like that. Brawl has ludicrous things. Project M does too. Smash 64 is beyond ridiculous at times. Smash 4 may have the lowest amount of crazy stuff... oh, wait, no, it really doesn't. Not by any significant margin. It's flashy, it has tons of combos, it's insane at times. Like the rest. Melee is not actual intimidating, people refusing to explain how they did crazy stuff is. I don't watch videos at all. I just play against people and larned by reading what buttons to press at best. I figure it out on my own. Frankly, every single video for every game I watched looked just as nuts. And they almost never explain stuff so they're worthless. This is not specific to Melee and never was. It's a bad argument because it's common for every game that doesn't show the controls outright. Smash or otherwise.
That, and you ignored everything else I said despite being true. Advanced Techs won't help you win by themselves. Pure and utter skill will. Of course you're not going to win competitive play without immense practice. If you don't want to practice, don't join those tourneys. They are not the only way to play and Melee is perfect for casual players by itself. I have tons of fun without doing anything more than the Techs(Pressing Shield when you hit the ground and immediate go back up your feet due to this). That's the only specific one I'm used to. And it takes no effort to get it right. You just need to practice it in the heat of battle, which is pretty easy. Now, applying when to use the roll version or just immediately getting up actually takes skill. The skill that all competitive players need, to read the opponent correctly. No amount of of techs will ever help. That's something you learn through facing them only. Even in casual play, that helps if you actually want to win sometimes.
For the record, the only videos that intimidated me were Brawl, and that's because I can't understand how people could approach or get KO's off. It was too defensive and the game looked horrible because of it. Every other game looked really easy to get into and figure out. I felt like I could do something by watching the videos. Brawl? Not really. It's why I went with power characters in it, since at least I could KO sometimes. That's not even counting how unbalanced the matches are by a severe degree since the game just has no decent character balance to even a remote degree. The other 3 games didn't lack this, so they felt very easy for me to get into. Nobody felt beyond awful or unviable. Brawl is the most intimidating game to me that I ever played. And it still is. I avoid tourneys for it entirely because outside of playing Snake, Lucas, Wolf, Squirtle, and Ivysaur, it quite literally brings nothing interesting to me to the table. The tier gaps are so wide that actually playing it competitively feels impossible. The other 3 games never had anyone that so broken as Meta Knight or so terrible as Link/Zelda/Ganodorf that it was hard to get into. By the time you actually see any real competitive match, you'll learn the hard way your favorite character may be completely worthless. That's way more intimidating than some video, knowing you practically cannot play a character without being waffledstomped.
