We like these LEGO themes and think they are some of the coolest and best selling themes of all time ever released in the world. Great for collecting and investing!

Top 10 Best & Popular LEGO Themes

1) LEGO IDEAS Theme

LEGO IDEAS initially started off as LEGO CUUSOO. It was later rebranded as LEGO IDEAS. Basically, users submit their LEGO project creations to the LEGO IDEAS site. If the project reaches 10 000 supporters within a certain timeframe, it goes on to the LEGO IDEAS review stage. A few projects are then selected from LEGO at the LEGO IDEAS review stage. They would then become official LEGO IDEAS set. These winning and approved LEGO IDEAS sets would then be sold to the public. The original LEGO IDEAS set creator receive 1% of the product royalty net’s sales. LEGO IDEAS sets could be licensed or non-licensed. They are primarily recommended for those that are aged 18+. These are great LEGO themed sets to collect and potentially even to invest in. We chose LEGO IDEAS theme to be the #1 top LEGO theme because the LEGO sets are fan designed project creations that are voted by LEGO fans.
