Go Digital
Permit me for a moment to extoll the virtues of the digital RPG book.
Sure, it’s not as pretty. However, it has a lot going for it.
Picture this: You’re in the fifth hour of your roleplaying session. There are pens, dice, coffee cups, soda cans, and books all over the table… especially books, because the Tremere in your troupe is a Thaumaturgical nut job who needs like six books to take any action. But! What if you could easily search all of your books on your MacBook Pro, because they’re in digital format? With a few keystrokes you can bring up whatever obscure ritual or piece of occult he needs and get back to playing. Or, even better: you have a lovely binder containing all Thaumaturgical knowledge compiled from your various books, which you can toss his way while still referencing your own copies.
Also, if he spills his coffee all over your copy of Blood Magic, fuck it – charge him a few dollars for a ream of paper and re-print that sucker.
Another point I’ll make: World of Darkness Classic is out of print. The only way you’re going to find it is used. They may wind up being expensive and difficult to find. If you want to game today, digital copies can be in your hands in as much time as it takes to type your credit card number, and usually for about half the original price. As an added bonus, some of that money goes back to White Wolf, and helps support the company that made the games you love so dearly.
My favorite source for digital books is DriveThruRPG. Quick and dirty, and they’ve got it all.
