For some reason I can't help but imagine gameplay mechanics from Jedi Outcast/Academy creeping in, like right clicking with a saber will throw it at a cost of energy (like using the Force meter) or equipping tech to mimic various Force powers (Force Jump: Press and hold Space to jump higher at the cost of energy/Force. Force Lightning: Press and hold F to shoot out a fan of lightning at the enemy) and probably the tech "cards" that allow you to use them would be holocrons.
