There are six jedi (Obi-Wan, Anakin, Ahsoka, Plo Koon, Kit Fisto and Mace Windu), and you can take any two you like each mission. C-3PO and R2-D2 also make a playable appearance, with R2 handling the hacking and threepio offering a few fun dialog trees. The story is also new and not half bad, revolving around the theft of a shipment of lightsaber crystals and a shadowy cabal of force-using goth mommas called the Nightsisters.
This definitely won't make you forget about the climactic moments of the original Clone Wars animated series, but it could help ease the sting of realizing most feared gangsters in the galaxy have be redesigned as offensively "comical" giant slugs.
