Two of my very favorite Star Wars experiences were watching the first Ewoke movie as a kid and playing KOTOR 1 on XBox as an adult. I loved how these stories delved into the Star Wars Universe without the constraints of having to tell the bigger story. It's partly the appeal of Empire, too, since that is the middle part of the plot it can explore extra areas of the Galaxy without having to deal with Tatooine or the Death Star. While the original Ewoke movie is clouded by nostalgia and would probably suck if I watched it today, KOTOR was produced with incredible skill. I'm in favor of the spin off movies as long as they are well done. I could enjoy seeing a glimpse of Han's home world and the 3-breasted purple alien chicks he banged before Leia tied him down.
