I should get that, if I can find it... '80s to mid '90s Castle was the best.
I bought a lot of castle legos back then, but haven't bought any since the early '00s, one or two of the Knights Kingdom sets... I do still have my castle lego stuff set up, though -- mostly stuff from the Crusaders/Black Falcons through the Dragon Masters and Royal Knights. Most of the stuff I had was military, but I did have the Town Wall Tavern (aka Guarded Inn), which was really cool; sadly, it's one of the castle lego sets I couldn't manage to put back together again (I'd used the parts in other stuff I'd built, I assume?), so I don't have it assembled.
