nagmumura,bakit?
imagine playing paintball or airsoft........... better yet, being in actual combat, when people get hit, (which unfortunately, most often they're dead, if not injured) they yell profanity.......... in a video game, when you get hit......... you're out of the game temporarily.......... and that sucks so people use profanity. at least, that's how we are when we play. hehehe.
that's how it is too when we have wargames in the army. when we get hit, it doesn't sting but it just make this annoying and constant beep on our M.I.L.E.S. equipment. and man, it really suck. hahaha!
