#RPGaDay August 17, 2017
I tend to collect rules to study game mechanics and not necessarily to play. So I am going to cheat here and change the question a bit to “Which RPG have I owned the longest but not played in forever?”
My answer would be Behind Enemy Lines (FASA 1st Edition, 1982). I last really played this game with my high school friends (i.e. pre-1985). I pulled it out recently as part of my RPG Retrospective but I haven’t “played” it since the mid-80’s. I really should pull it out because it appears that it could be a good firefight generator for several skirmish-scale wargames.
