Minecraft: Story Mode will be delisted from all of the game stores that currently offer it for sale. It is a sad but not uncommon occurrence for many modern video games after a number of licenses expire. Unfortunately, the case of Minecraft: Story Mode goes a step further. It seems that people who have purchased the game will not be able to download it again once it is delisted.
“On behalf of the publisher, Minecraft: Story Mode – A Telltale Games Series, Season 1 and 2 will no longer be supported on June 25th, 2019. If you have purchased these seasons, please download all remaining episodes prior to the service being discontinued in June.” – Related
