You guys sound bitter about Halo. Why? Is it because Microsoft bought Bungie?
I still appreciate a good collector's edition of a game. The extra $10 for a DVD with commentary by the developers and just going behind the scenes has been appreciated. Sometimes we get extra goodies like an art book and or figurines. Decent bonuses for $10, IMHO.
Granted, we definitely see a lot of special editions of games these days, especially on the 360, but for a game like Halo it's necessary. I don't think anybody understands or appreciates the rich backstory of Halo as a game and how it was conceived. Just watch the MWSF video, the E3 video (can't remember the years for either of those videos, but it's from when it was Mac/PC only), and the video about Halo from its original RTS design and how it evolved (with commentary from developers). There is so much that happened behind the scenes for this game, it disappoints me Halo will be remembered for it's multiplayer game instead of the single player game. Bungie made a very decent sci-fi story for Halo.
Yes, maybe the Legendary edition is overdoing it with a Spartan head, but I want to see that extra disc full of content. If I come across it for the right price, I'll jump on it, but until then, I will have to accept my already discounted Collector's version.
