Likely much like many that will read this my opinion has changed a great deal in the last few years. When the PDF first arrived on the gaming scene I hated it. It was slow to load cumbersome and just plain annoying to have a big ass laptop taking up a huge chunk of space on the game table.
Fast forward a few years and tablets become the rage and laptops go from mobile monitors to notebooks. Add to that the industry becoming savvy with PDF design and they are far more welcome. In one swift stroke gone are the days of lugging milk crates from car to table. Not only do we have all the books we need for the game session in one simple fast to access place. We likely have our whole gaming collection on that one device.
Books both softcover and hardcover are great but at some point, if you are like me or several of my fellow gamers. You have to look at your gaming wall having expanded from one too… 2, 4, 6, 8 bookshelves of games. At that point, you have to decide. With PDF’s saving you so much potential space. Maybe just maybe it is time to convert some of that collection into PDF and only keeps your most used books.
So these days I reserve my physical books to the settings I know that I am going to spend the most time on or collector books such as my Hardback Rifts books as well as my Leather bound D&D and Cypher Systems RPG books. I consume most of my RPG content digitally now.
