Are the iwads in Doom 3: BFG Edition Modified?

If you try to see it from the perspective of the developers it makes sense. The BFG Edition WADs are essentially the same as those from the XBLA port (you can see the same censored secret levels in the Xbox version).

The patching of 31 and 32 must be very recent because they originally were not patched in the XBLA version.

In fact you can even play xbox live between the BFG version and XBLA version, but they had the tendency to desync due to having different enemies. A fine example of why this is kind of a "big deal" to Doomers, it breaks some pwads too.
