Thank you very much for your great review!
But I´m really angry about all this annoying "steck-is-better"-rubbish. Steck is not as stable as SysX- you definetely can´t carry a 3666 castle in one piece!
And if you take this set 4866 f.e.- its camparable to former 3667 3667 - Small Castle as the small castle and in price- and now don´t tell me that 3667 has more features or is bigger!
Everybody can buy and build with whatever he likes best- but this steck-lamentation everywhere throughout different threads is really nerve-racking!
I don't know where you get that System X is more stable then steck.
My SysX falls apart all the time, But my steck does not.
And you can pick up a 3666 without it falling apart.
I can pick up my castle in one piece and it is bigger then a 3666.
But what really makes these castles better is that you can expand them,
like I did with my 3667, I now have two and another steck castle.
All of it I made to look quite impressive in 1 castle.
Can you do that with these?
If you buy two, can you combine both castles using every part to make a new better castle?
No, you cant. You may be able to combine some part, and make a few things larger...
But you wont be able to use every single piece.
You would have bought two castles, and in the end had to waste 1/2 of one to make it bigger.
