This kick-ass mini came with the core game Imperial Assault. Like most Fantasy Flight games, it uses D&D dice but with goofy symbols on them instead of numbers. For me, I just picked up the game and expansion packs to have Star Wars minis that are better made then the WOTC random boxes.
One day I hope to get a Star Wars game rolling with the best set of RPG rules, WOTC’s revised 2002 edition they rolled out right before Attack of the Clones hit theaters. There were slight changes to the game (probably 3.5E ideas) but more importantly, the Gamemastering section provided the details on Clone Troopers and the Separatists’ battle droids.
Why WOTC over say the reprinted WEG or the current FFG editions? I like what WOTC did, if you know how to play D&D/Pathfinder, then Star Wars isn’t terribly different with the core game mechanics.
