quote from the book "Basic Knowledge of CS "by Valve, first published on November 9, 2001.
Page 14, line 7:
"CT side has the advantage to just wait for T's to walk into their positions since they only have to defend the bombsides. T side needs to occupy a bombspot, plant the bomb and defend it until blast. The disadvantage for T is equaled by an easier economy. Better guns for less money."
