Mark Butler: "I still have fond and vivid memories of the fun, informative game manual that came packaged with my PlayStation copy of FPS classic Doom.
"It had cool artwork. It had in-depth descriptions of enemies, weapons and environmental artifacts. And it had a really well-written short story that provided context and background for the cut-scene free campaign.
"I found my mind whimsically turning back to that manual this weekend, as I contemplated the trend for modern games to arrive pretty much free of any additional printed background or world-expanding lore – unless you happen to buy the Collector’s Edition, that is."
