Q – Ignoring IW.net, is the PC version a direct port of the console version?
A – Mackey-IW: No, PC has custom stuff like mouse control, text chat in game, and graphics settings.
No Mods, no console, no “lean” no self-hosting, no nothing. You may as well buy the console, because it is piracy proof! Wait, did you say piracy proof? Why is it all over the net being played on hacked Xbox 360s? Shoot! Doesn’t that mean that this crappy negative-featured version is hobbled for no god-damned reason at all? Yup!
