I got the free first episode of Minecraft Story Mode. Now I want to buy the next episodes but I can't because I need a Season Pass that I can't buy again. How do I get the other episodes?
Unfortunately you will not have any luck anymore. The developer Telltale had to file for bankruptcy some time ago and put dozens of employees on the street overnight.
Since most of the games of the studio were licensed titles (including Minecraft), the availability of the title has been severely restricted for months, since no resale was possible without clarification of all rights. Starting tomorrow, all titles of the studio will disappear from the well-known platforms and will no longer be available for sale.
