Marauder 2107, Witchcraft, Nephilim, Legacy: War of Ages, Hong Kong Action Theatre...if you were an indie RPG studio in the late 90's, early oughts...I'm one of the three guys who bought your book and tried to get people to play it.
EDIT: Add to the list: Albedo and Justifiers. And this isn't even getting into the games with cult status like Amber: Diceless Roleplaying, Torg, or more "mainstream" products like just about anything made by Steve Jackson Games, ICE, Chaosium, FASA, or White Wolf, lol.
Heck, I can pile a lot of TSR games on the list like Star Frontiers, Top Secret, Boot Hill, Dragonlance SAGA, and the Amazing Engine games...not to mention this cobbled together fantasy game with ten thousand supplements...there were two versions published simultaneously in the 90's and competing against each other...man, what was the name of it...
