This game could have had potential. But like all movie games, they develop them in 2 weeks and put 'em on sale. The real story from the books is very cool, and could have made a really interesting game. And while Sierra manages to touch on some elements from the books, they fail to capture the epic feeling of Eragon. And some things they changed (in my opinion) made the game worse; for example: they changed the Ra'zac to bugs, when in the books they are really birds. Sierra also fails to mention some integral characters from the Eragon world, like Roran, the Twins, Nasuada, and Katrina. Overall this is a really a bad game altogether. If you dont like bad graphics, repetitiveness, jamaican people, weird art styles, and bad camera angles, this game is not for you. One of the only plus sides of this game is the fact that is has easy cheevos. The story could have been better (it was changed a lot from the books), and the voice acting is pretty pathetic.
Cheevos- 9/10 (so easy!)
Edit* Thanks Salty Old Dog for pointing out that you need to run through the game at least twice, because the difficulty achievements are not stackable.
Although this game is based off a movie, the movie was based off the book series which is a GREAT series. This game is a complete insult to the books.
