I was rather blown away by the quality of the fan made Star Wars Roleplaying Game Revised Expanded Updated REUP. What a time to be alive- when people have the time, talent, and drive they are let loose to create something that is actually a better product than the original book.
Thank you to the REUP Team.
Covert Ops for Modus Operandi a couple of years ago, discovering that it came very close to being a remake of Top Secret/S.I. With a few of the variant rules in place it is almost exactly TS/S.I. Just the skill system is different.
