This takes up a floor space in my basement a tad over 8 feet by 8 feet. There's an additional 2 feet between the back wall and where the city starts so that I can get to the circuit breaker in the corner. The skyline behind the whole thing is just a couple pieces of black matte board cut in a series of vaguely building-y shapes.
With the exception of the figures suspended from the ceiling, they are all simply balanced in place. I seem to have developed a knack for getting figures to stand on their own.
The playsets have been collected over a period of about 15 years. I recall getting the Wayne Manor set when I was interning at Kenner back in college, and the Enterprise bridge about a year later. Anything older than that was purchased via a secondary market long after the toy was discontinued. The single most expensive purchase was the Hall of Justice; it was given to me as a gift from Mom and Dad, but I'm fairly confident they paid over $100 for it.
Yes, you are seeing some licensing clashing there. That's largely the point. There are figures representing Marvel, DC, Hanna-Barbera, Bone, Firefly/Serenity, Scud, Muppets, pirates, Judge Dredd, Dr. Who, Battle of the Planets, Max Headroom, The Goon, Hellboy, Tomb Raider and probably some others I'm forgetting offhand.
- I actually wanted to make the Enterprise into a SHIELD Helicarrier. But as the only SHIELD figure I have is Nick Fury, that didn't seem to make much sense.
- I have a Ghost Rider figure as well, but I managed to snap his leg off while I was putting this together. It should be fixable; I've had to repair Blade, Baron Zemo and Green Lantern from essentially the same malady.
- Three of the four firemen's arms are actually broken at the shoulder and are currently just resting in place. I'll need to attempt to fix these, but it'll be a trickier issue than GR's leg.
- I've got several more pieces, sufficient to make a waterfront, but I've run out of room. Not sure if/when I'll be able to incorporate those at any point.
I could go on about all sorts of things relating back to this, but I'll spare you the intricacies for now. Feel free to ask questions in the comments here, though.
