Hardcover, softcover, digital, what’s your preference?
I’m a huge fan of electronic books — portable, carry on multiple devices, searchable, easy to store. But sadly electronic RPGs have not always kept up with modern technology — large format RPGs with multiple columns are very poor for iPads and useless for my Kindle. I’m not at all satisfied with my Feng Shui 2 pdf since it’s not printer-friendly and not tablet friendly either. Some publishers are getting it — Kevin Crawford’s recent releases of Sine Nomine titles have included epub, and a lot of small press publishing is in digest format which is well suited to the tablet (e.g. LotFP).
The main value of electronic books are getting hold of OOP copies. These days I’m going back to hard copies, a lot of PoD. Right now I’m waiting for a softcover copy of Courtney Campbell’s Perdition (with illustrations by Russ Nicholson, woo!).
