Eragon is easy to learn and once you master it, you won't have long before you finish it.
If you don't play these games like me, it will take you a couple of days to finish the game. But, it still won't take you that long. The graphics were okay. They could have been better, but by game standards, it alright. The only part of the graphics I liked was how the game Saphira looked just like the one in the movie. I was also glad that the game was just like the book and not the movie, since the movie cut out a lot of the parts that were in the book.
From my standards, I thought the game deserved a rating of 7 for how some might find it challenging and how well it was based off the book.
