I've got a lot of nostalgia for these kind of micro playsets. I had 5-6 Mighty Max playsets back in the day (some of which are still intact) and definitely a few of the Star Wars ones. I don't know how much I played with them but they were always fun to set up and have on a shelf. There's something intrinsically fun about having a movie set rendered in miniature form.
Took me a while to find a complete version of this Observatory playset. People tend to lose all the little accessories easily which is understandable so it means wading through tons of half complete sets on eBay. Glad to finally have it in my collection but it doesn't feel quite as fun or packed with features as the three Batman Forever ones.
The scale of the figures is very small and the playset feels a little bit... empty. It could have really done with a trapdoor or missile or something extra to bring the whole thing to life.
There's two more Batman & Robin microverse sets out there - a Batcave one and a slightly larger Arctic Gotham set. I'll keep my eye out for them. I'd really like the set of micro figures too (shown in the video) but I can't find these anywhere.
