What is the LEGO® Master Builder Series? (MBS)

What exactly is the LEGO® ‘Master Builder Series’?

When LEGO® gave us details of the UCS betrayal on cloud city last month it mentioned it was going to be part of the ‘Master builder series’  but we had no further information about what that was or what it would entail, which has led to LEGO® fans asking what exactly is the ‘Master builder series’?

Well here is the official statement from LEGO® Group

“The Master Builder Series models are large playsets and besides being complex builds they are characterised by having many play features and functions, interior details as well as a range of minifigures. Ultimate Collectors series will remain highly detailed display models providing complex builds with a focus on authenticity and both Ultimate Collectors Series and Master Builder Series will continue as a way to highlight the unique characteristic of each style of model. [sic]”

So basically it looks like UCS will continue to be complex large playsets, but the MBS series looks like it will be for large-scale playsets that are for play not for display. It’s a bold and overdue move by LEGO® Group, finally distinguishing between large-scale models that are for display and large playsets that you can actually use. We will certainly see some new playsets such as the imminent betrayal on cloud city’ have the MBS acronym.
