Hi, my name is copacetic and I buy ttrpg material which I never actually play. What is wrong with me?
Sure, you can tell me nothing is really wrong as long as I get some enjoyment out of it. What is going on though. Reading RPG books makes me dream of wonderful session which could happen. Ironic that it is a fantasy about fantasy.
If you enjoy reading it and imagining what you could do with the system then it’s no worse than buying any other book, reading it and putting it on a shelve to never open it again, is it? Don’t worry so much, enjoy what you can while you can!
When I was in middle school I think I owned every D&D 3.5e main book and many of the “complete X” books despite never playing and never intending to. I enjoyed reading about how the multiverse and magic worked. I also enjoyed looking at the cool pictures. It really tickled the imagination.
