Game: MechWarrior (third edition – FASA, 1999)
My Experience: I will admit to having owned the first two editions of MechWarrior, and even having built characters in them, but I can’t recall ever playing before third edition. Back in the day, Little Sister ran a somewhat hyperbolic campaign in which I and Methrys were the primary players. We may have invented the new war crime of planetary-scale psychological warfare.
