I think whether or not someone likes F:NV strongly depends on what importance is placed on gameplay. Fallout 3 has terrible gameplay. This includes the combat system, controls, itemization and progession system. F:NV doesn't fix these points. I just has better writing (not that hard) and supposedly good fractions (I wouldn't know as I only played the first couple of hours of the game). For some, this is enough to make F:NV a good game. For me, it's not enough. I hated Fallout 3 and F:NV just doesn't fix enough of the former's flaws.
