I really liked Fallout 3, and New Vegas is more of that wrapped up in an Obsidian burrito. A little internally serious, far more interested in letting you non-violence your way out of things with speech, science, repair, medicine, and bartering. A few more bugs per hour, but not all that bad, of course this is who knows how many patches later, plus I'm playing with the unofficial patch off the nexus. This one has me looking forward even more to Pillars of Eternity, after playing Alpha Protocol and Southpark this year.
