Having watched ANH for the first time in over a year yesterday it got me thinking just how few scenes have been done as playsets.
Its easy to think about making big playsets but I was thinking more along the lines of smaller playsets, these include:
Turbolaser Turret from the first Death Star:-
12-18 inches high with detailing on the outside. The upper half rotates and is large enough to fit a Death Star Gunner, with detailing of the two guns on either side of him. Gives you something to shoot at your X-wings/Y-wings etc. You could even make it connectable to other death star sections as described by others.
Rebel Hoth Turret:-
Similar to the idea above but with battle damage panels, gives your ATATs some target practice. It could be similar to the vintage version but instead of one turret you could have two, one at each end of the base with a section of trench in between. Probably best to make it more to scale than the POTF2 version.
Hoth Ion Canon:-
Okay its not gonna be the smallest set ever, but it wll allow the Rebels to outgun the Imperials for a change.
Bespin Cloud City core Vane:-
Including breakable window, fall away handrails and lightsaber damage.
On a creature front you could do any of the creatures/beasts from the chess board on the millenium falcon from ANH.
