Review: Stunning, majestic and highly detailed. - Mega Construx Castle Grayskull is an awesome homage to the original playset from the 1980's, yet based on the modern rendition of the most recent Mattel's Masters of the Universe Classics line. I like the idea of mini possible figures, since it doesn't take so much space either for display or for the kids to play with it. It does have a lot of play features and assembling it was a joy, it will take a significant amount of time to put it together. The good: 1) The artbox. The art and attention to details on the packaging is beautiful, from the inner sides to the instructions booklet. 2) The instructions. The bags are numbered and assembling the castle was easy, although I would recommend adult assistance if you intend on purchasing it for a child. There were a few challenging moments. 3) Very detailed. Every level and part of the castle is very well detailed, from the throne room, trap door, jaw bridge, dungeon and elevator to the weapons rack. Everything is aesthetically well placed and looks stunning for a plastic brick style playset. 4) The included figures. He-Man, Skeletor, Beast-Man, Man-At-Arms, The Sorceress, Green Godess and even a Zoar figurine. The play set comes complete with a great selection of figures. And even if you already have some of these Mega Construx figures, these are uniquely painted and exclusive to the playset. The bad: 1) The price tag. $250 for a playset is very high, but as fans of a toy line that isn't getting much attention compared to those with movie tie-ins filled with hype and merchandise, is a price well worth it. Overall, I highly recommend getting this playset for your kids, if you'd like to introduce them to Masters of the Universe, or if you're a fan and collector. The Mega Construx line is well worth it, highly detailed and of durable quality. I will definitely be supporting this line, not just for nostalgic reasons, but because they're much smaller in scale, and brings a lot of fun and joy to the family.
Review: An amazing build - First up, it's not Lego. The Brick Quality is not as good. Mega has come a long way from the crumbly polystyrene bricks of the early Halo days. They are now using ABS, the same material as Lego. But the feel isn't the same. The bricks have mach sharper edges. It takes much more force to connect and separate them then with Lego. Your fingers will really hurt after building a massive set like this. But in many ways it's worth stepping outside the Lego comfort zone to see how another company designs something on par with Lego's D2C or Ultimate Collector Series sets. A few other words of caution. While yes it looks like that cool playset you had when you were 9, this is very much an Adult/AFOL level set. There is very little color variation throughout the build. It is thousands of very small hard to differentiate parts. Where guessing wrong on a part will have you undoing 2 hours worth of work. This is an Adult tier building set. Even putting the figures together will require an adult. Do not buy this for younger kids. I would say a very advanced 11 or 12 year old, or better yet 13+. With 16+ being ideal. The younger crowd will love playing with it when done, but getting it there is challenging. The set itself is amazing. A magnificent mix of recreation of a classic toy, mixed with some really clever brick building design. It's a lot of really great brick sculpture and architecture, all in muted shades of sand green. The set is huge when completed. Roughly the same size as a Lego Modular Building. It's a Dollhouse design. And it perfectly recreates, and improves on the classic Castle Grayskull playset. Every detail and feature from the original toy is recreated in brick form. And at a scale that allows for more figures in play. Inside the big gorgeous box, covered with wonderfully rendered art the set is broken down into 4 smaller boxes. Each smaller box contains 10-20 numbered bags. So Mega has finally followed Lego's lead in that regard. Be warned, it isn't quite as smooth as Lego's. With each bag you will find lots of parts left over as you move on to th enext. Those leftovers get used and absorbed later into the build. So you are never quite clearing your active parts tray. It's a little harder to keep organized than a big Lego build. The instructions are a massive square bound book that is almost 2' wide. Which makes it awkward to find a surface to sit it on to keep open. Make sure you have really good lighting as well. Some of the part colors are very subtle. You will need good light to tell what is called for in the manual and to tell the pieces apart. The build is an education in clever build techniques. Mega has a broader assortment of SNOT pieces, which they use in some interesting ways. It's a fun build. A little tedius at points, but very rewarding as the various sections come together. Particularly intriguing is it uses some tricks and techniques that you would only ever see in Lego fan MOC's. Not in actual sets. Such as the rounded tower build. The versions of the figures included in this set are from the original He-Man toys and the comics included in the toys. So Teela is in her original Green Godess form, not the cartoon version. Man At Arms doesn't have his mustache, etc. Other figures available in the line are cartoon correct. The exclusive figure to this set is the Sorceress. Overall this is a great set. And will look impressive on display alongside many of your Adult tier Lego sets. Yes it's Megablocks (or whatever they are called this week?) But it's among the best that Mega has offered and well worth adding to a collection.

## Questions & Answers

**Q: How much was the original price when it came straight from Amazon?**
A: The original MSRP was $250. Right now it’s shipped from and sold by Amazon, so this is probably the lowest you will be able to get it. Scalpers have had it $400 - $500 over the past year, so grab it now if you want it. I just did. :)

**Q: Will It be avalaible for preorder in any other European  Amazon online shop before the release date?**
A: It already has been released

**Q: How well does this hold together for play?  does it fall apart easily like lego’s do? or does it hold together well without adhesive?**
A: Theyre pretty similar to legos..my opinion tho,I like them better than legos..the figures anyways

**Q: Hi why shipping cost and import feeds are so high? I would like to buy it but from Italy is completely a mess, quite 200$ for shipping and fees**
A: Shipping is high because its large and heavy, the import fees are levied by your country, Italy,

### ⭐⭐⭐⭐⭐ Epic
*by P***E on January 5, 2023*

I kept my eye on this set for a long time wondering if the value was worth the money. I was a Masters of the Universe fan as a kid and have several of the other Megablocks sets, the scale is a lot of fun. I finally decided to get this set and I am very happy I did! This set is epic. The book for instructions alone is a massive tomb with over 1,000 steps! It took me 5 days of working a few hours a day to get this set completely constructed. If you are used to building sets like this it will be no problem. The instructions are clear and easy to follow. It's so huge it just takes time. The features built in to the set are just what you always wished for when you were a kid. Dungeons, elevators, trap doors and secret passages all add up to a ton of fun. If you are a building set fan and a MOTU fan this is a must. Spend the money. You will not regret it.
