>>8436238As a kid from the 80's, I managed to find most of the larger set in fleamarkets. Despite dating from the late 90's, their building style is closer to the early 90's castles. The mix of castle and cart / siege weapon with silly aspects like gliders reminds me of the first ghost and dragons. They use some large pieces (rock slope, burps and wooden panel) to give a nice size just like the old castle wall panels and the builds are just as interresting. That theme doesn't suffer the plague of other sets of the era like juniorized builds or random assemblage of parts like the late space sets or the time cruiser theme.
To me it is an underated but short lived theme, that would explain the low demand.
The big castle, side tower and bridge sets are nice display pieces.
