Solid journalism and a truly fine portrait of artistic collaboration, perhaps the best I have read. For better or for worse, the trilogy of Wolfenstein 3D, Doom, and Quake transformed computer gaming, and at the heart of it were two very different guys named John who hit one of those rare perfect grooves. Call them the Lennon and McCartney of gaming if you like; Carmack’s programming genius and Romero’s visceral sense of game design came together uncannily well, and part of the fun is reading how neither of the two could later replicate the experience alone.
