I really hated that he called Another World a rip off.

I echo that sentiment, the Karateka journals were awesome to read.

Second on Masters of Doom; my favorite part is near the beginning, when Carmack showed Romero the smooth scrolling on a PC, and Romero is running through the office trying to show everyone, only for most of them to be largely unimpressed. I thought it was telling that the only person who really understood what Carmack had made was Romero, and it showed why they (initially) made such a good team.
