Managing anger and video games?

the same thing happens to me when i play mw 2...like a camper using the one man army perk using land mines to Surround him and uses the moniter attatchment and is a sniper with an rpg...oh that crap pisses me of!!! why play when your gonna play like a low life at least run away...ive ran around the whole map and only died 3 time with 20 + kills its not that hard you just need to gain skill...thats an honarable way to play not like being a camper...no honor in tat...quick scope kill is weird to me their honorable yet its still get me mad cuz thats an instant kill...idk playing online were gonna meet alot of people with honor and low level scum that really have no reason to play but idk i think the honor among gamers has changed due to online gaming...i remember playing nintendo and there were things we would not do cuz of respect but know that respect or honor is kinda taboo know...its sad really know we dont know who has skill and who just camps or quick scopes...(i say quick scopes because all they ever use are sniper classes and nothin more)...a great gamer is someone who can master all kinds of classes...but thats just me...=]
