Betrayal of Darth Revan is a game I've tried to get on the table for a couple of years now. It's a WotC RPGA module that was created for GenCon 2008 (timed to coincide with the release of the Knights of the Old Republic Campaign Guide for Saga Edition). For those familiar with the Star Wars Expanded Universe (EU), that is the novels, comics, video games, etc. set in the Star Wars universe, the module takes place not long before the start of 2002's Knights of the Old Republic video game and is a key part of an event that appears in a couple of cut scenes from the game.
It's a fabulous adventure that was released by the RPGA when they ended support for the Saga line. It combines a little of everything that makes the Old Republic era great in the first place, Jedi vs. Sith, lots of aliens, space battles, ground battles, the works. I've never run or played it before, but I've read it and can't wait to put it on the table.
The fortunate thing about this one is I've got very little prep to do. Print the maps, create my usual hints one-page to give neophytes a primer on the rules system, print the character sheets and the adventure text, and study the adventure in depth.
As for what led me to choose it? I figured, with the release of the MMO, that there might be renewed interest in the Old Republic era, and that this would be a good, easy to do tie-in to the game. It also acts as a pretty good overview of the system, and looks like a rollicking good time.
