*sigh* The smack-talk has arrived. Yay.
I, for one, get my enjoyment out of playing a game, not strictly from winning, from pwning n00bs, or whatever. I try to never smack-talk, because if I smack-talk I either wind up taking away from others' enjoyment of the game and looking like a sore winner, or I end up looking like an idiot when I lose.
It's altogether a more enjoyable experience if everyone practices good sportsmanship, plays to have fun, and tries their best to not say things that will make others feel bad.
