Pretty Good Deal...
Even if you don't like Final Fantasy XIII, you can more than likely take it and resell it for store credit at a big box store, and you're still getting a top-of-the-line 360 plus store credit at a box store for no charge. Otherwise, if you can find a better bundle on New Egg, go with that.
It's a game, the 360, two wireless controllers, AND a new 250GB HDD; Basically you're getting the game for free
The game is Final Fantasy XIII; which looks really good; but you spend the first 20-30 hours walking in a straight line and pressing the "A" button; occasionally; pressing up or down
