The Ewok Village was also pretty cool. It had the net trap at the bottom, which was really cool, and then spit for roasting guests over the fire, a throne to honor whoever the latest visitor to be mistaken for a diety is, and then a few more drop traps for the unsuspecting Stormtrooper prowling around in the poor little Ewoks huts (I would alway imagine there to be spikes at the bottom).
Most SW playsets were kind of pointless (see, Droid Factory, Cloud City, Rebel Command Center, Cantina Adventure, Jabba's Dungeon, etc.), but the Death Star and the Ewok Village went above and beyond what a playset should be. If my parents are going to throw alot of money away on something, it ought to at least be able to keep me occupied for a decent amount of time.
Another cool one was the exploding speederbike. Blowing that thing up and watching the rider go flying never got old.
