Over all an excellent review. Perhaps a tad long in places, but never terribly so.
Minor nitpick: It seems like you did a lot of comparisons to Fallout 3, which gave me the impression that you hold Fallout 3 as the standard and were comparing New Vegas to that standard, not on it's own merits.
Mayhap it just seems like you did a lot of comparing because the comparisons were spread out across the review. In that case, it might be better if you condensed all the comparisons into one or two paragraphs, and then went on and reviewed the game as a standalone, as though it had no relation to Fallout 3.
