Old 40K and fantasy models, but you already knew that. I also collect RPG's that I will never play, D20 modern & sourcebooks, Twilight 2000 & 2013, various zombie apocalypse RPGs, although I sold all my old never used 2nd ed ADnD books a while back I still have all the WHFRP V1 and 2 books although I did actually use them a bit, same with Cyberpunk 2020. I also have all but the very latest releases of Dark Heresy and Rogue Trader, I'll never play them, I hate the system and gosh darn it if I don't hate the twisted mockery of what once was the setting has become but I still buy the fucking things. I draw the line at Deathwatch, but it took willpower.
