“If you are a fan of modular buildings, and especially if you have been collecting them for the last 10 years, you are going to get this set no matter what. Despite falling into that category myself, upon completing Assembly Square my feeling was largely one of disappointment... More over what feels like a missed opportunity. As the 10 year anniversary set, 10255 was given a higher price point and piece count than any of these sets before.”

“This is awesome. It's hard to believe designer Jamie Berard can keep pulling these out of the bag. This special 10th anniversary model is bigger than ever before - just over 4000 pieces sitting on a 32x48 base - and in many ways, is better than ever before. For starters, it... More has a brilliant array of completely new LEGO pieces, some of which fans have been dying to own for years.”
