How to simulate the Codex Astartes?

[How to simulate the Codex Astartes?]

I may be just throwing out my thoughts, but every time you see the Codex Atartes mentioned throughout Games Workshop fluff it's never spoken of as being more than one book (at least that's the way it seems to me).  I also thought over the years of reading about how the Ultramarines adhere to this particular way of war, that they follow the great tome as laid out by their primarch.  So if there are different versions, it just seems likely that the Ultramarines would  stick to what Robute Gulliman wrote and possibly other Ultramarine commanders over the millennia.  Again thats just my way of seeing it and I'm sure there are tons of you who will disagree.  I see it as a book, a big f****n book.

Sounds like FFG is the one to stick with.  Thanks for the info.  I really like the old GW games like Advanced hero quest and Talisman to mention a few.  But it seems that FF is taking content from the GW company and either expanding on old games like Talisman or Warhammer fantasy role play, or making new ones which totally rock like Dark heresy etc. etc.  I guess what I'm trying to say is I'm glad GW had the sense to allow another company to start making games based on the warhammer and WH 40k universe.

on a side note: I watched a video review on Descent: journey in the dark.  And I had a flash back of Advanced Hero Quest.  So yet another interesting game has come from FFgames.  I'm really starting to like these guys.

I was wondering if anyone could shed some light on the differences between the two versions of the game.  I'm sure they are similar but how much are they alike?  I also want to know if FF version comes with more gaming miniatures than the GW version.
