I don't think you understand. but, that's ok. I only became interested in the game after reading previews in magazines I trust such as PC Gamer and XBox as well as, reading previews online at sites like 1Up. While Halo had more advertising, perhaps, I am not interested in purchasing that game. I'm not even sure they are comparable.
You can bash Obsidian if you like, I'm not sure what purpose that serves you, but, whatever lifts your spirits. Based on the News Release it appears Obsidian did their part and turned in a finished product, which Sega has decided will be released much later. Now, if they intend to keep working on this Title at Obsidian, well, that would be a different story.
Want? Wanting something has very little to do with it. I expected the game for which I pre-ordered. I have since cancelled that pre-order and frankly, after eight months when it is released, I may not care that much about this game because I may have plenty of other gaming options to keep me busy.
