It was enjoyable to look at the artwork that served as the foundation for the game, although it was extremely light on text/explanations. Most pages have at most a caption, so it is very different from other Star Wars Art books I've read. I would've loved hearing from the artists about their inspirations and other aspects of the decision making process. At first I was worried there wouldn't be much in terms of concept art, but there ended up being quite a bit in the form of "here are 10 different ideas we had for their outfit". I really liked that the people who made the game seemed to be big Star Wars fans themselves. Multiple comments mentioned how, when there were using locations that previously existed, they wanted honor the work that had come before.
The downside for me was that quite a bit of the book just looked like a painting of what you saw in the game. They were beautiful, but if you played the game it feels like I've seen this exact thing already. I suspect over time my feelings would change on this. I would love a book that had scenes from Ocarina of Time, Morrowind, or Halo to be able to enjoy beautiful paintings of some great games.
