Let's talk about that engine. New Vegas runs on the same basic framework that powered Fallout 3 and The Elder Scrolls IV: Oblivion, and it brings a lot of technical weirdness up from those games. Less than an hour in, I was staring at a guard, pacing back and forth to guard his post... 20 feet off the ground. Enemies clip into the ground with an alarming frequency, often making them impossible to shoot. The game--a retail disc running on a new-model Xbox 360--crashed on me about a dozen times over the 33 hours I spent playing, often taking a significant amount of progress with it. The load times and frame rate seemed to get randomly worse as I continued to play the game, with some simple scene transitions taking 20 seconds or more. The technical hurdles you'll have to make to stay interested in New Vegas are meaner and more frustrating than any Deathclaw or Nightkin you'll face in the game. If you're the type of person who likes to watch for a patch or two before settling into a game, know this now: you probably don't want to play Fallout: New Vegas right away.
