I started consistently playing RPG's in 1978 (late '76 start with war-gaming) and increased my RPG exposure through the 80's. I've played such an incredible amount of games, its too many to list. I still gravitate towards epic realistic, gritty fantasy and sci-fi (with a twinge of horror for flavor). I like to play 2-3 times a month. As such, most of my dev efforts are around my own created system.
