After about 30 hours of L4D i must say it's kinda repetitive and boring.
As people play more they like to "Experiment", in turn they do stupider stuff, care alot less and try and be the hero.
Knew this would happen... but iunno it's getting boring now.
Versus is incredibly boring if you're team sucks. It's never a close game, theres always one team winning by like 3000 points and the other has like 100.
