It's pretty well-known that you shouldn't drop by Bungie's offices unannounced (or even, usually, announced) - they aren't open to the public, and you'll just be wasting your time. Unless, of course, you're Nathan Fillion. Then you can drop by. This, and other interesting info, can be found in this week's Mail Sack - there are some great questions, some silly questions, and answers that span the gamut. There are also a pair of new desktops for your viewing pleasure. (Actually, only the thumbs are in the Sack - the desktops themselves are in the Wallpaper gallery.) Go read, and get pumped - E3 is coming in less than a month!
