I don't understand why people bash CS
Because it's crap. The weapons are unrealistic. The movement is unrealistic. The levels are overly simplistic. I could go on and on.
It's popular so it doesn't suck
That's shit logic. It's popular because Valve is pushing it at the people who are content with crap games, ie: those that haven't played anything else. It sucks for reasons given above.
Every mod has lamers,not only cs
True, but CS has a far greater percentage.
