I guess i'm a jaded old man at this point, but I can no longer read impressions of a game from the developers mouth, and truly get excited about any of it. If this was some random journalist, I might get more excited, but i've just seen it too many times before, and let's face it, developers are usually in love with their own game. They think it's always great, and always looks amazing, and all of that.
How many new mothers do you meet who say "God, this kid is a pain in the ass, he's not cute, he's not smart, and lord only knows if he'll ever amount to anything". :lol
Of course not, so you should take developer "blogs", and the like and think of them like a mother talking about her new born child. It's always the bestest, most cutest, and pefect thing ever created.
With all of that said, i'm still very excited about Halo 3, but i'm just taking that very "let's see the goods" approach to the single player this time. I want to see this game be stunningly awesome, and I expect to find out when the first reviews begin appearing. Until then, i'm sure i'll find myself reading these comments from Bungie and replying with a shrug.
