The chance to play Fallout: New Vegas has been hard to come by -- we've seen it in action before, but it wasn't until a little while back at a pre-E3 event that I was able to finally grab a controller and explore Obsidian's take on the streets and surroundings of a post-apocalyptic Sin City.

But it turns out, as I wandered into the dingy casinos and off into the desert for a few quests, that I had already played the game anyway, back when it was called Fallout 3.
