Development Story of Doom 3 (in 3 parts)

who reads this blog for longer knows that I`m a fan of id software. I found this 3 part documentary on youtube (2007?) about their development of Doom III. Now there is rather critique given on this sequel, as talking about the change in new game R@GE but it`s true that this sci-fi horror atmosphere was amazing. And based on old-school shooting action with great looking levels and creatures.
