The one thing I liked about Warcraft story was that there were only a few contradictions in the story between the books and games. The books really just fleshed out what happened in the games, and also filled in holes.

Now the problem with Star Wars is that with so many different types of canon it just goes all out of whack. I'm not sure about the canon scale, but I know The movies and what Lucas says is the the most canon, then it goes down from there. But what is more canon, the books or the games? What happens when one contradicts the other?

Books are usually more canon and usually when it comes to games the only reliable information is the cut scenes.

Books and games both occupy the same tier of Canon, "C" Canon. They're considered canon unless contradicted by the Movies or television products.

C-canon is Continuity Canon, consisting of all recent works (and many older works) released under the name of Star Wars: books, comics, games, cartoons, non-theatrical films, and more. Games are a special case, as generally only the stories are C-canon, while things like stats and gameplay may not be;[7] they also offer non-canonical options to the player, such as choosing female gender for a canonically male character. C-canon elements have been known to appear in the movies, thus making them G-canon; examples include the name "Coruscant," swoop bikes, Quinlan Vos, Aayla Secura, YT-2400 freighters and Action VI transports.

Official levels of canon

The Holocron continuity database is an internal database maintained by Lucas Licensing for the express purpose of trying to maintain continuity within all licensed products. The Holocron is sorted into four levels of canon, reflecting LFL's current canon and continuity policies: G, T, C, S, and N. G, T, C, and S together form an overall continuity that is considered by Lucasfilm to be the "true" Star Wars canon.

G (George Lucas) canon is absolute canon. This category includes the six films, some of the deleted scenes from the films, the novelizations of the films, the radio dramas based on the films, the film scripts, and any material found in any other source (published or not) that comes directly from George Lucas himself. G canon overrules all other forms of canon when there is a contradiction.

T[1] canon refers to the canon level comprising only the two television shows Star Wars: The Clone Wars and the Star Wars live-action TV series.

C (continuity) canon refers to the main body of EU work, and is the next most authoritative level of canon. All material published under the Star Wars label but not falling into either G, S, or N is C canon, and is considered authoritative as long as not contradicted by G canon. Games are a special case as generally only the stories would be "C-canon" while things like stats and gameplay are "N-canon". If the video game has several possible ends or if the player can choose the gender or the species of the main character, only one of each is considered C-canon. C-canon elements have been known to appear in the movies, thus making them G-canon. (This includes: the name "Coruscant", swoop bikes, Aayla Secura, YT-2400 freighters or Action VI Transports.)

S (secondary) canon refers to older, less accurate, or less coherent EU works, which would not ordinarily fit in the main continuity of G and C canon. Unless referenced by a G or C-level source, the story itself is considered non-continuity, but the non-contradicting elements are still a canon part of the Star Wars universe. For example, this includes The Star Wars Holiday Special, the Marvel comics, or the popular online roleplaying game Star Wars Galaxies and certain elements of a few N-canon stories.

N continuity material is also known as "non-canon" or "non-continuity" material. What-if stories (such as those published under the Infinities label), game stats, and anything else that is directly contradicted by higher canon and cannot at all fit into continuity is placed into this category. "N-canon" is the only level that is not at all considered canon by Lucasfilm.

You're welcome.
