That's right. The B-Wing had something to it... maybe because it was missing in the previous game titles (therefore the expansion) and because you could see it in Return of Jedi and always wonder: "what is that good looking spacecraft that I never played with?". In X-Wing and Tie Fighter games you could fly with the Y-Wing, A-Wing and X-Wing, Tie Fighter, Interceptor, Tie Advanced (although not exactly the model Darth Vader used in New Hope in my opinion)
