yea i played a lot in long stretches, but i also played very fast. shit practically every mission youd have to drive with someone id have to park the car and wait for their dialogue to finish up before driving into the mission marker. i also would just grab whatever and smash away unless you were forced to eliminate every enemy. like if you had to blow up trailers, id just blow them up and smash away instead of going in cover and shooting it out with 30 dudes, lol.
i dont know how call of duty is now but i beat one of them in 6 hours, lol. id be pissed if i got a game for full retail, like $60 - 70 and beat it that fast. it was that one where you die at one point cause a nuke goes off. and the end is on that bridge where you kill that one guy at the last possible second
