Old Republic scientist had invented cloining technology hundreds of years before the stories we (unfortunately) see on movie screens today. However, some of the test clones were unstable and prone to strange mutations, so the senate quickly banned the technology across the galaxy. About 50 years later, The Old Republic started receiving reports of strange, armor-clad warriors attacking some of the outer-rim worlds. When they send a team to investigate, they are quickly overwhelmed by hundreds of MANDALORIAN WARRIORS (yes, the same place where Boba gets his armor). The Republic immediately retaliates by sending it's entire fleet against the invaders and soon discovers that the dreaded Mandalorians have uncovered the secrets to the Republic's old cloning technologies and have been mass-producing their soldiers (so the clones are the BAD GUYS in the original tale) After decades of fighting, the Jedi and the Republic defeat the Mandalorians, but at heavy losses. Where once there were thousands of Jedi roaming the galaxy, now less than 100 remain. With the severe destruction caused to so many worlds during the Clone Wars, trust in the Old Republic's governing body and its Jedi defenders is at an all time low. This gives a young senator named Palpatine his chance to turn the people against the Jedi and the politicians against each other. With so few Jedi remaining, it is easy for his new apprentice, Darth Vader. to hunt down and destroy the rest of the Jedi.
Holy asteroids, why didn't Lucas use this as the basic plot of his prequels (maybe changing the name of the Mandalorians) instead of what we actually got?
