I am big fan of reading and I spend a lot of time with books. I also like bibliographic book and this is one of the best book of this genre I ever read.

Book cover two Johns who create Doom and also Quake or Commander Keen: John Carmack and John Romero. It starts in their childhood where Carmack tried to burgle a school to stole Apple II and Romero spent all his time playing games in arcades around the town.

Story continues with their first games (both of them makes a lot of games alone (maybe 30 - 60 of them)) and then they finally get together while working in Softdisc publishing company writing games together. Later they created Commander Keen and they create ID software and then is all well known story.

Book is great and author must spent enormous time of researching the topics. I do not see much biographic books which have this depth and also still funny and pleasure to read it. And it also cost as low as $10 on Amazon
