Started to play in 1980 with D&D my DM had the white box and we switched to AD&D a year later. Got my Moldvay box at 12 and stared to DM right there and through all editions.
But I have played:" Star Frontier, Star Wars WEG, Call of Cthulhu, Black Eye, Vampire the Masquerade, Werewolf the Apocalypse, Heroes, Marvel, Palladium games ( Fantasy, Rifts, Supernatural, Robotech, Nightspawn and a few others), GURPS, Role Master, Space Master, Paranoia, Warhammer and a fee one shot tries I don't even remember their names. I do have the Battletech RPG and the technical readouts but never acually played... So yeah, I did play a lot and still play a lot.
