The purpose of this is in regards to the consideration of the concept of releasing a reasonably priced (say around AU$20) DLC pack to existing Doom 3 owners. As a value added reward to existing loyal customers.
Especially those that are older than ID as a company, that became fans with Wolfenstien in the early 90's. Such people that own, as well as played to death, every PC game ever written by ID.
I am sure that the new content of Doom 3 BFG edition will make a profitable, as well as keeping the fans happy, will be considered to be a good idea by all that read this (except the haters)...
