I rarely buy systems anymore, as I have so many (ok, maybe a dozen) systems I own, haven't read, and will probably never play: Over The Edge 4e, Cepheus Engine, Dolmenwood, etc etc. I also have game systems I HAVE played, but doubt I'll play again - Torchbearer, Dungeon World v1, GURPS 4e, AD&D etc. Finally there's the category of systems I have read but doubt I'll play - Ironsworn/Starforged, Macchiato Monsters, the Veil, etc infinity (it seems like).
However, I do LOVE to read adventures. I read them like static "choose-your-own-adventures".
That said, now that I'm on this side of 60, even that might be too far. I've got 250+ fiction and non-fiction books, a dozen graphic novels (with more in the various series on the way); as well as 3 shelves worth of rpg adventures and systems to read. And notwithstanding 5 regular monthly/bi-weekly games (depending on game); doubt I'll get through all of THOSE either.
All of the above aside, the last time I got rid of rpg books, I got rid of my Monster of the Week books. GUESS WHAT my next rotating GM group's GM picked to play?
