The game is supposed to take place between ANH and TESB. I noticed that several levels though are same(except for the planets) as some of the missions in the Rogue Squadron books. First of all book two "Wedges Gamble" one mission has them attack an imperial moon base orbiting Kessel. Then game level 6 "The Jade Moon" attack an imperial moon base. It's not just those similarities, the book says you have to protect the commandos until they take over the base. The game says the same thing. Since Rogue Squadron books were created before the game it looks like they copied from the books. So some of the Star Wars Rogue Squadron books have good tips on how to beat some levels in the game. The same mission as the book just with different names.
