Oh definitely. The killstreaks were such a prominent and powerful part of the game that it's probably the biggest reason why people act obnoxious in Modern Warfare 2 and, in some cases, Black Ops. Who can blame them though? Killstreaks are the most consistent way to do well in the game so people will do whatever they can to obtain them.
Ha, I love the AC130. Something about raining hell to the enemy team in an awesome explosives shooting monster makes me feel so good when playing. The UAV is such a good killstreak though, especially in Free-For-All.
Aw damn, I'll hopefully be joining you tomorrow. Have fun and good luck. :)
