Nothing fancy here for Mirror's Edge and its inevitable collector's edition. No tin boxes, no action figures, no unlockable outfits or in-game trinkets. No, Mirror's Edge is keeping things practical, offering you a CE (provided you preorder it directly from EA) that for $130 will get you the game and...a bag. An awfully nice bag, made by Timbuk2, which is also a bag that's a replica of that used by the game's courier starlet, Faith. It won't beat out other CEs for quantity of goods, but it certainly has them beat on the quality front.
The only special collector's edition I've ever purchased was for Halo 2 and after spending the extra $10 I never understood why in the hell I spent the extra $10. Now they're asking ridiculous things like an extra $70 — which is $10 more than the game itself costs and the game itself is $10 more than games used to be before the "next-gen" tax was added when the 360 was released.
If a game is popular/anticipated enough to have a collector's edition it's never going to become rare enough for that collector's edition to be worth anything. Not to mention, all these things are are the freebies critics and journalists get at gaming conferences, etc. Charging for promotional material — that's rich. I wonder how many "Legendary" Halo 3 helmets you could find at the dump if you went looking.
