Love Copetti. Even as someone who is not particularly knowledgeable of everything he’s talking about, I I really enjoy thumbing through his writing and diagrams. There’s just something really fun about trying to understand what is going on under the hood with these machines, especially fifth and sixth generation consoles

Did read this years ago and read it today again. Just so happy that there are people producing such quality work. Even if I personally don't know much about any of it, I still find myself being totally sucked in while reading.
