Minecraft is the best example of Microsoft’s modern approach to gaming platforms. The publisher acquired the block-building phenomenon and developer Mojang in 2014 for $2.5 billion, and it has since shaped that investment into one of its most active live services. The growing Minecraft Marketplace is at the center of that.

Each month here at GamesBeat, I take a closer look at the Minecraft Marketplace and its best-selling content. You can take a look at past results right here. For December 2017, a few new downloadable worlds and mashup packs made the list. Winter Mini-Games Festival by Noxcrew rode a seasonal wave to get on the charts just behind the Summer Mini-Games Festival. Mojang’s own Norse Mythology Mash-Up also made the list after debuting last month.

But the big story of December is that not only did Blockception’s Whiterock Castle repeat as No. 1, but this creator also took the No. 2 spot with The Crater.

If you’re wondering what Blockception’s secret to success is, well … I asked the Blockception team.

“Honestly, we aren’t really sure,” Blockception creative director Alex Bellavita told GamesBeat. “We love that people are downloading and enjoying our content. Everyone in the team works hard on making sure that the content they make is to their best ability at the time of it being conceived.

Here’s the top 10 best-selling items on Minecraft Marketplace. As a reminder, Microsoft provided this data, and it represents the most-downloaded paid content from both the community and Mojang.
