War seems to have changed quite a bit between Fallout 3's original ending and this new content. There're more giant robots, for instance. The orbital strike seems like a new thing as well, considering that my personal Fallout 3 character was so hideously evil that had orbital strike technology been available they definitely would have used it on me.
Perhaps Ron Pearlman is just talking about the word "war", which definitely hasn't changed in awhile. In that case, I say we all start spelling it "whar" just to take him down a notch. He's been getting all uppity ever since they gave him a giant stone arm.
Broken Steel will be available tomorrow on Games for Windows and Xbox Live for 800 Microsoft points.
