The censorship is for germany that wants to barry the 1940's, they don't care about the gore they just want to forget about the nazi party all together, I'm not saying there right, I'm just saying its not the gore they care about. The game was what 6.9gigs, and a dual layer can support up to I think 8.5gb, and if size was a issue removing doom 1 and 2 would only save you 40mb

.
I don't remember Tim Willits saying that he took those parts because of the difficulty of those sections, do you have a link? In which case if he did say that, especially before the release, then you knew what you were getting when you bought the game plain and simple.
I was not talking about censoring Doom1/2.
There was a rumor before release that ROE in the BFG got censored or heavily "modified" because it had some ratings problems in Germany when it first got released in 2004. That's why i brought this up.
The sections in ROE missing have no content that could be linked to the Nazis or whatsoever.
Btw.: Germans don't censor Nazi symbolism in games to make germans forget the "1940s". In fact it's the other way around.
Adolf's face and all his "showbiz" is running on TV over here all day and all night to make sure germans never forget what they did back then...
As for Tim Willits' statement about lowering the difficulty for Doom3 because he himself was such a bad gamer, you might wanna check his interviews on youtube pre release of BFG.
I also recall reading an interview where he said this. Give me some time to find the link.
[EDIT]
The content limit on 360 DVDs is about 7 GB. The rest of the storage is reserved for copy protection mechanisms.
The 360 is the best selling console in the US so it's the main target platform for the BFG edition.
Skipping Doom1/2 would have spared between 40-50 MBs on disc. This would have been sufficient to include the missing ROE content.
