It's actually kind of disturbing how angry people get after losing just once. No offense to anyone, but sometimes it actually makes me worried that TV's and systems are being destroyed simply because a player can't beat an opponent. With all due respect to all players... these are... grown adults... throwing remotes and trash talking other people... because his or her character got KO'd. People are going to argue that Smash is an activity like any other, but seriously, it's a video game. It could be classified as a sport, but there is virtually nothing physical about it unless the player makes it physical.
Before making accusations, I am not bashing on any competitive players whatsoever. A lot of players are humble and very accepting/mature when they lose a match. However, some people take it to the extreme. I understand it's his or her passion to play Smash, and they have all the right to persue that passion... but it's kind of crazy to see just how seriously it can be taken. We should all just learn from our mistakes, just like we should with any other activity.
