I loved Masters of Doom and bought Jacked hoping it would be as amazing. Jacked had some great personality profiles in it... but as mentioned above, the personalities just aren't as captivating as Carmack and Romero. Plus there was a lot of focus on Jack Thompson (the video game activist [1]), which got tiresome. I hadn't realized that the title of the book was a pun on carjacking and Jack Thompson.
The book also didn't dig nearly as much into the detail around the creation of the games. In Masters of Doom, you felt like you were watching Carmack and Romero invent Doom. In Jacked, the game creation process was talked about in much more general (and less personal) terms. That's absolutely typical for a journalist, but Masters of Doom set such a high bar for gaming journalism that I ended up a bit disappointed.
Overall Jacked was a worthwhile read, but I didn't find it to be in same class as Masters of Doom.
