Christ, where do I begin...?
Console wars. Everything I have ever heard from a console war is utter trash and nonsense. It serves no useful purpose. The best console in the world will not be decided by these blithering twats, SO STOP IT!
Console/PC wars. Same, only the over-zealous console-users mentioned above fight it out with their PC/Mac/Whatever counterparts. Also, same response to them all, because no amount of debate will solve this EVER!
The "Such-and-so game was built for such-and-so system and doesn't belong on any other" morons. These people piss me off because every time they speak, their voice changes into fart-sounds and a big yonker grows out of their forehead. (i.e. They're talking out of their ass.) If a game company put said game on multi-systems, then it was made for them all. This is another form of degradory remark to attempt to make their system look better. Shut up. You're just annoying.
Likewise, the "Such-and-so game is god of all and everything else sucks" overhyping jackasses. I cannot touch Halo because it's surrounded by an inpenetrable forcefield of people that won't shut up about it. I'm sure Halo is a good game franchise. Unfortunately, the way people behave about it is as disturbing as obsessive WoW addiction and so I will not go near it. Funny comedic machinima is my limit.
Finally, people who BS alot for both winning AND losing (especially if they're a controller-thrower) have no right to speak to me. It is a game, it is meant for entertainment. Jokingly complaining in a non-serious manner to lighten the mood and be a good sport is fine. Outright bitching will be looked upon with disappointment. I suck at some games and excel mightily in others. I do not piss people off either way, nor am I ever pissed.
(Just as a note, this is not aimed at any person in particular on a personal level. If you find that you exhibit some of these traits which I hate to hear or deal with, then it does not mean I automatically despise you. I would only do that if you personally went out of your way to do all these things in an asshole-like manner. If you have these qualities, don't show them to me. I remain courteous to those who are equally so. If you find that you are not of these qualities explained above, but feel I offended you somehow, then I apologize. It wasn't aimed at you, but rather the jerk who's intensely out of whack.)
