These sets are awesome and personally, I can't get enough of them! I don't have kids, but I originally bought these because I thought they were too goofy to pass up.
After the first set (the Wampa), I was hooked! Anyone who says they're not interested should check out the Millenium Falcon set. It has fantastic play features regardless of what number childhood you may be having.
If Hasbro is listening, PLEASE MAKE MORE SETS AND WHEN YOU DO, MAKE SURE THEY MAKE IT TO STORES IN QUANTITY! The only complaint I have with this line is how difficult they were to locate.
