No, actually, trash talk is NOT part of the game. Trash talk is an element of tournaments, not the games themselves. Idk if you read
Wobbles's blog (I'd love to hear what Wobbles has to say on trash talking as well), but he actually talks about how tournaments are an artificial element used when determining who the best Melee player is. At one point, he justifies the usage of tournaments as a means to determine the best player because "Performing well in high-pressure situations is an unbelievably important life skill that translates to everything you do. Measuring and improving it is arguably more useful to everybody involved than figuring out who the best player is."
I think the question about trash talking comes down to whether we feel the same. Is being able to perform under pressure an important life skill? Obviously. What about performing when others are cheering for your opponent? I would say so. What about performing when you are actively being demoralized by virtual strangers, but your opponent is not, based primarily on where the competition is taking place or the tactics you use? I just don't buy it that that is an important skill. It certainly
is a skill to be able to ignore hate raining down upon you, but it neither seems fair nor relevant to someone's Melee abilities, so the reason that it's tolerated on any level is beyond me. I realize I don't have any credibility to discuss anything on these forums because I'm not a talented player or Melee personality, so hopefully someone on the podcast's panel feels similarly and can convey this point in the discussion.
