That's tough for me because I love collecting and reading rpg books. Yes, I'm incredibly boring. I have numerous books from different genres, and many editions of some of those. The older the series, the more interested I am in acquiring and reading it. There are some that I have read through repeatedly; like my Pathfinder 1e CRB. Others have gotten one solid read through followed by occasional perusing. I get the reasoning that too many is just too many to deal with, but I've just come to accept that this is my hobby now.
