Sun Tzu's ramblings apply to all forms of war. I use some of his more famous writings in every game I play, ranging from L4D2 to SupCom. Admittedly the guy has a bit of an ego, stating that his writings are the magnum opus of warfare advice and basis, but they kinda are if you look at them. It's kinda like a fortune teller, everything they say is right, but it may not be anything extraordinarily specific; I.E. Laser Towers. There's a reason most military academies still use his (translated) writings as a textbook.
