I was wondering if I could purchase the collector's edition of New Vegas and then use the cd key to validate it on steam? I have grown accustomed to using steam as a way for me to organize my game library, and I want to be able to use all of their features to manage my game. This will be the deciding factor for me, as i am torn between the digital version on steam and the Collector's Edition (Poker set ftw!!!)

All versions of Fallout NV are integrated with steamworks (i.e. : Steam is required to play).

So yes, you can.

nevermind

Sweetness, thanks very much
