They are nothing but lies and fables made up by the Man to oppress the people. But seriously Im sick of hearing it every other sentence, the usage of the word is overly saturated and doesnt even mean anything. In other sports or competive events they have intangibles in smash everything is mindgames this mindgames that.
And I love all the psuedo analysts that can see the "mindgames" or lack off, by watching a couple of videos. Also it seems others use these "mindgames" as a blanket of comfort against their lack of technical(another annoying word) ability.
In short I think anytime the word mindgame(s) is used it should be substitued with some other dummy word(like the gay wii thing). This will not solve anything as the context will still be the same but it would be somewhat amusing.
In closing as the late rick james, parodied by chappelle, would say **** YO' MINDGAMES!!
I'm tempted to agree with this guy - partially, anyway. Mindgames DO exist in Smash; they exist in every competitive game that's ever been made. However, the term "mindgames" comes up so often and is misused so often that it's evident that many people don't actually understand what they are. I hear "mindgames, mindgames, mindgames" so much it's disgusting sometimes.
Mindgames are elements of Smash that transcend the physical "mechanics" of the game - the problem is, the mechanics of Smash can be pretty difficult to master on their own. Knowing the mechanics of Smash means you know which moves to use to counter your opponent's moves, you know which move has priority against another, you know how far your up-B recovery jump will take you, you know the relative cooldown time of each of your attacks, etc. etc. etc. Basically, what I'm saying is that knowing the MECHANICS of the game well can get you quite far...very far, in fact. The trick is to be able to "put into practice" your knowledge of the mechanics, and if it weren't for MINDGAMES, we'd ALL be able to do that in a relatively short amount of time.
The concept of mindgames is not nearly as "advanced" as most people make them sound. Mindgames occur in each and every game of Smash, from the lowliest newb to the loftiest pro. All games have mindgames. If they didn't, we'd essentially be like supercomputers, playing each other and rapidly calculating the probability of the most successful move, etc. etc. etc. Of course, we're not. There's something else that gets in the way, and that's mindgames. They're not advanced; in fact they're childishly simple when you actually think about what's going on.
What ARE mindgames? Well, you can classify them as one of two things (they're actually different versions of the same thing, but oh well):
1. "Predicting" what your opponent will do, either through pattern recognition or from past experience with such a player, and making them pay for it. If you're Link and you notice that your opponent is constantly dodging your hookshot attempts, you can punish him/her for doing this by, next time, using up-B instead of the hookshot. Your opponent, meanwhile, has not really been applying mindgames in dodging your hookshot; he is following the MECHANICS of the game and doing what he knows to work. And it does work, until you pick up his pattern and turn it against him. Of course, some might say that you yourself would be following the mechanics of the game just like he was. True, you are - but you are also able to pick up on the patterns he's using and take advantage of them.
2. Keeping yourself "unpredictable" (a.k.a. "tricking out" your opponent) - essentially, another version of #1. While in #1, you predict what you're opponent will do, here you make sure that your opponent can't predict what YOU will do. This is much harder than the first, because you actually have to be thinking like your opponent and ASSUMING that they will be attempting to use "Mindgame #1" on you. If you assume that they're using this but they're NOT, you'll suffer for it. However, if they ARE attempting to look for patterns in your play, then you stand a good chance of throwing them off guard. Let's say you're Link again and you come down with an aerial on your opponent's shield, and then use your hookshot. You grab him, and he thinks, "Crud - next time he hits my shield with an aerial, I'll dodge so he can't hit me with his hookshot." At this point, you should be thinking, "Okay, so he's gonna try to avoid my hookshot. Therefore, I'll up-B so I can hit him in his dodge." And the next time you come down on his shield, you up-B instead, and hit him out of his dodge. Obviously, this won't work every time. But the very act of keeping your attack patterns random will cover you more than if you tried "playing by the mechanics" of the game and simply repeating things that appear to work. Because if your opponent is actively searching for such patterns, you're dead.
3. The Psychological Factor - this involves playing on the weaknesses of the human mind. Spamming projectiles to frustrate your opponent and getting them to do stupid moves that they'd NEVER do if they were "playing by the mechanics" and actually focusing on the game. Doing little "wavedash routines" to intimidate your opponent (especially if they're incapable of wavedashing themselves). Using moves like Marth's forward smash frequently to keep your opponent on edge and nervous. This category of mindgame is probably the simplest - it involves the least amount of "mindwork", and people can often reap the effects of this mindgame without actually KNOWING that they're using it.
So we now reach a point where we know what mindgames are: the art of predicting your opponent's actions, while keeping your own unpredictable, and attempting to scramble your opponent's calm/focus/cool by using certain styles of play. All this ON TOP of knowing the mechanics of the game inside and out. I think that what separates the top players from everyone else is their ability to put into practice the mechanics of the game while simultaneously remaining aware of the mindgames. Sometimes, if you focus too hard on "mindgaming" your opponent, you pass up lots of easy opportunities to punish your opponent just by using the mechanics of the game. Likewise, if you try too hard to play "by the mechanics", you end up using lots of predictable patterns that are easily punished by your opponent. The best players can tread that fine line between MECHANICS and MINDGAMES and know exactly when to use what. For 99% of Smashers, that's nearly impossible to do. That 1% is the portion of Smashers that can do it.
And please - no one can say after seeing a certain video that "such and such a player was mindgaming/being mindgamed at this point." Sorry, but you DON'T KNOW - perhaps that player made a stupid mistake; we're all humans. Perhaps that player used a move that he/she didn't MEAN to use, but luckily worked anyway. Perhaps that player was playing by the mechanics when he should have been mindgaming. Perhaps that player was mindgaming too hard and passed up some easy hits. You just don't know from watching a video what was happening. You can guess, but there's no way of knowing whether you're right or wrong about it.
There's mindgames for you.
