ID avait pour habitude de travailleur sur 1 jeu à la fois, on sait maintenant qu’ils travaillent sur plus ou moins directement 4 projets (quake 4, doom 3, wolfenstein, et un autre jeu) ; c’est sur ce point que HomeLAN a questionné Marty Stratton de chez ID :
Marty Stratton, the director of business development for id, told HomeLAN Friday that it not that much of a change for the company. « id did work closely with Raven back with the Heretic and Hexen games, » Stratton said, « Both those titles were similar to what we are doing with Nerve, Gray Matter and with Raven again. »
