I like the colection of weapons, and think the remaining parts could be well used for other things - ox carts, ice cream factories, ....
It could use at least one more fig with it.
I would never have bought this just for the payability factor, but my son and his friends like this one.
If it was ever re-released, I would only buy it if it was a very low price, and then primarily as MOC fodder.
I am sure I have seen some deals on these at the used catapult lot down the road ...
