This is probably the easiest out of all the wishlists
Easily the easiest--at least out of the OT, anyway.
Unlike the other two, there's no big "creature scene" to have to choose characters from, and we spend a huge chunk of the movie with just a handful of characters: Luke, Artoo, and Yoda on Dagobah and Bespin Han, Chewie, Hoth Leia, and Threepio on the Falcon. And a few of the waves over the last couple of years have knocked a bunch of the other characters out, too.
Empire's really getting to be pretty tapped-out as far as figures go, I think. Just a handful of minor background characters left, along with some much-needed resculpts of the main guys (Bespin Han and Bespin Luke, for example: Kick-ass figures when they came out in 2000 and 2002, respectively--but they're really lacking when compared with what Hasbro's done in the last couple of years.) And those outfits the main characters wear for five seconds at the end of the flick. . . Years ago, I thought it was really silly that anyone in their right mind would actually want a Lando Smuggler figure, and now here he is in my Top Ten.
Contrast this with Star Wars and Jedi--I could pick totally different Top Tens for both of those and be equally as happy with them. . .
