I'm concerned about this because a lot of the background to characters in the original trilogy still falls under EU, doesn't it? I mean, Zuckuss' ability to use the Force to find his quarry and even the fact that he teams up with 4-LOM is never stated in the movie. That's completely EU material. If Disney erases backgrounds like that, I believe it will have a profound affect on this game.
For example, if Disney decides that Trandoshans don't hunt Wookiees, Trandoshan Terror and it's associated cards suddenly don't make sense.
I'm not saying they will get rid of all that stuff, but if they cut off ALL EU, it would drastically change Star Wars as we know it. I'm hoping that, similar to what MarthWMaster thinks about Mara Jade, most of the species concepts and stereotypes remain. Otherwise it's like entering a whole new galaxy.
I suppose the answer to things like this would be to keep the essential plot points but do away with the stories wherein they occurred, so that you can have Trandoshans hating Wookiees and hunting them etc etc, but do away with, was it a Kathy Tyers short story that made this so? Same for Zuckuss and 4-LOM, have them as a team but do away with that actual story too. So all the new material that will be coming out can use that stuff to create new stories around it. So instead of seeing Zuckuss and 4-LOM join the rebellion, instead we can see them infiltrating Imperial Center to some end. Or maybe Zuckuss built 4-LOM?
I do look forward to seeing what the story group come up with as regards to what stays and what goes. I get the feeling that we might be surprised by how much is kept, but still.
