The Brothers Brick
“The Creator line takes us back to our roots with a simple build that’s simply excellent. There aren’t many fancy techniques here, and there aren’t many specialized pieces, but that doesn’t mean too many compromises on quality. It’s true the interior could use more detailing,... More but $100 seems like a sweet spot for a LEGO castle.”
Full review at www.brothers-brick.com
New Elementary
“The set features a new experience in terms of part usage and color scheme, but still captures the nostalgia. From a New Elementary perspective, there are some interesting recolors and rare parts. The only thing I’m not liking is the use of the 1 x 4 x 3 panels to fill the... More walls.”

About Creator 3 in 1

Creator 3 in 1 sets come with instructions for three different models from the same bricks, built one at a time. The trick is in the design. Every part has to work in all three models, so the tiger of 31129 Majestic Tiger also builds a panda and a koi fish, and many builders keep the parts from a set as a starter supply of ordinary bricks.

3 in 1 was introduced in 2006 and currently consists of 252 sets. As of today, 4997 Transport Ferry is the most valuable 3 in 1 set with an estimated new/sealed value of $304.
Summary
Creator 3 in 1 Medieval Castle set 31120 was released in June 2021, retailing for $100, but has since been retired. New, unopened Medieval Castle sets are valued at $130, while used sets can be found for $110 in good condition.
