An Assassin’s Creed game, except set in Star Wars, based around Mara Jade, the Emperor’s Hand, essentially already an assassin.
"Eagle Vision" dreck replaced with Force senses. Ability to make crazy dumb spine-shattering leaps of faith and jumps and block certain ranged attacks justified through force-sensitive dexterity. Sneaking up and jabbing someone from behind with the wristblades replaced with igniting your Lightsaber into their back. In-canon she’s already a master of combat, disguises, and infiltration, what’s not to like?
C’mon, it would be good.
