Mindgames in and of themselves are purely a player-based issue, and as far as I'm concerned, it's just performing an action to get your opponent to do a desired action. More correctly stated, some characters have more options, or more effective options for certain mindgames than others.No. Just no. This is entirely incorrect.
Some characters are much, much better at mindgames than others. The more maneuverable you are, the better you tend to be at them, for instance. Other attacks can also set up mindgames - projectile spam, for instance, as well as Snake's mines. Some characters have high mindgame potential, others low, so it is indeed a part of a character.
Take dashes for example - Sonic's running speed and 'screech stop'/side-B cancel can be used to bait an attack from the front, and punish the after lag. Ike's running speed is perfect for punishing a spotdodge by running across the opponent and performing a pivot grab from behind. Obviously, their dash speeds are too different to interchange those baits/punishments, though arguably Sonic can do a reverse side-B shield cancel grab to 'slow down' his grab (since normally, if you tried to run behind and pivot grab, Sonic would end up running past and pivot grabbing before the spotdodge ends).
As for Falcon, though it is true that if you have high accuracy and actually land your hits, Falcon seems like an amazing character, I'm not entirely sure what kind of 'mindgames' he'd be generally reliant on, aside from punishing spotdodges, and airdodges, since that's what everyone seems to do whenever you land a U-air and jump towards your opponent...lol
I think that might just have been a personal application/example.This isn't what a tier list is. A tier list is not about the popularity of characters but their effectiveness. A very effective but very difficult to learn character may be very high on a tier list, but that doesn't mean that they are particularly common to face - simply that someone who can play the character has a character advantage over a lot of the field.
If your area has alot of tier whores, you're most likely going to meet more high/top tier characters.
