I have not played the PC version but I guess you get used to the tools you have to work with and for me I only see the game the way it has been presented to me on a 360.
The PAUSE menu can make up for the lack of HOT KEY related stuff. As long as you pick your binds wisely for essential real time related items your good.
They could of gone that extra mile and supported the 360 CHAT PAD, now that would of been AWESOME!! Maybe next time...
