Meh, I'll pass on this one. I do agree there needs to be a caslte bucket similar to the Castle Dacta set:
That set was $80+ when it was available and it didn't really have all that much of use at the time. Heck, I still can't seem to find a construction I am happy with for the castle wall pieces in this set, likely where much of the $$$ came from it it. The minifigures in this set, well, they ain't my favorite.
I think a better solution is needed for Castle builders than a be-all-end-all bucket that would never satisfy our needs & wants and likely be too expensive. Perhaps $10 "boxes" with specialty parts could be an answer: you could have a Theme Parts Castle Brick box, a Theme Parts Castle Minifigure & Accessory box and a Theme Parts Castle Specialty Pieces box, much like this Creator Castle set. You could mix and match what you need for your own collection then with very little waste.
I like the direction I see LEGO going into with this small Creator set. It has a lot of useful parts and a really fantastic minifigure for troop or individual character purposes. At $10 it is a step in a positive direction if you are looking for some parts and small additions to your minifigure collection. The colors may not blend as well with the rest of the Castle collections, but they do go well with a vast number of the bulk bricks or Creator sets that kids likely have lots of. If I couldn't build a gray castle to my liking, these colors would certainly do fine.
More like this, and perhaps more specialized in the future! Please?
P.S. The Creator Pirate set from this same assortment has a nice selection too, and a good torso for Castle or Pirates.
