Throughout 2019, Microsoft experimented with building a real world, augmented reality Minecraft game designed in the same vein as Pokémon GO. Called Minecraft Earth, they finally opened it up to everyone in November of 2019.
In just a few months, it’ll shut down and all player data will be deleted.
So what happened? Writes the Minecraft Earth team:
Minecraft Earth was designed around free movement and collaborative play – two things that have become near impossible in the current global situation. As a result, we have made the difficult decision to re-allocate our resources to other areas that provide value to the Minecraft community and to end support for Minecraft Earth in June 2021.
In other words: this game just isn’t going to work in a pandemic. Pokémon GO might be doing just fine thanks to a strong foundation of super dedicated players and a steady stream of curious newcomers, but it’d be pretty damned hard to go from zero to sixty with a real world game when everyone is supposed to be staying at home.
What happens next:

The team is releasing one final patch that removes all in-app purchases and makes all in-game mechanics easier/faster
On June 30th, the game shuts down. Even if you’ve got it installed already, it’ll stop working.
On July 1st, they’re deleting all player data.
Anyone who has spent any money in Minecraft Earth is getting a free copy of Minecraft Bedrock version, and players who have unused Minecraft Earth rubies will get an unspecified amount of Minecoins that’ll work in Minecraft-proper’s marketplace

This will be our last update, so we made it a good one! Please enjoy and thank you for being a part of the community!
