We're going to rotate through the same info a lot now since everyone went to the same presentation. At least Joystiq is succinct..<blockquote>Speaking of making people happy -- New Vegas sees the return of the karma system from its predecessor, joined by the tracking of your character's reputation among the populace and various factions, including the Brotherhood of Steel, the New California Republic and Caesar's Legion. Depending on your standing with these groups, they'll do everything from ordering hits on you to treating you like royalty when you visit them. Companion characters are also back, though this time you'll have a new "companion wheel" you can use to quickly issue them a wide variety of orders, manage their inventory and more.</blockquote>
