i got the game on the day of release (pc version), happily go to install and then discover i need steam to activate. my internet is sporadic and weak, so finally today, a week later, i was able to install. now i know it's odd to have a pc capable of playing new releases reliably and not have a decent net line but that's the situation. question is, can i play FNV when my net is down?

Yes you can play "offline"

You should go online once awhile though when you launch the game to get patches here and there like as of now

awesome. thanks
