The gunplay has always made the difference between a good first-person shooter, and an amazing one. Even in the Call of Duty franchise we've seen some debates about which game brings the best balance, and what games could have been better balanced across the weapon set. Hardcore COD4 players might find their bread and butter in either the AK or the M4, but you'd be hard pressed to find many guys that go straight for the G36 or M60. Those players are out there, but they're few and far between. On the pistol side of things, most players in my clan run with the wooden handle 45; the iron sights seem to be a bit more forgiving, and it hits just as hard (if not a big harder?) than the standard USP.
