This would be a tough, less engaging read for folks who never play(ed) video games or did not grow up during a time when these games were evolving and exploring different facets of technology and playability. Fortunately, I'm the target demographic, so I adored the references. It's worth noting that the themes of isolation, anger, grief, love, and friendship transcend the focus on video games, and to me that's the most beautiful part of the book.
