Here are all of the ripoff's I found leebarr
Star Wars: Young Farmer (Eragon, Luke) lives with Uncle, the Empire as it is commonly reffered to comes and kills his remaining family, and the young farmer becomes the first new member of an ancient organization that died out recently when some of it's own members turned evil and overthrew them. The farmer sets off on a journey with a former member of the organization who has been in hiding for several years to watch over the boy. They are trying to find the rebels and after the old member of the organization dies, primarily defending the young boy, the boy reaches the rebels and they fight the empire in a massive battle in which the rebels win, and the farmer performs a seemingly impossible task (killing a shade, shooting lasers in through a small hole). Part 2 involves the young farmer going to recieve higher training from a member of the ancient order that is even more powerful then the member he travelled with in the first book, the stronger member also trained the member the farmer travelled with in the first part. That plot could fit to both Star Wars 4 and 5, and Eragon and Eldest.
