In the Nitrado app on the xbox, I can see additional games for which I can purchase a server, such as Minecraft and 7 Days to Die, but those games do not show up as available for game switching. Is there a reason for this? Are they going to be made available?
Nitrado lists ALL games available as a hierarchy, and then during the process pick what platform to use. If it is not available, you will not be able to switch to it. As when it may or may not be available is really dependent on the game creators offer to their partners, or whether or not Nitrado is going to carry it. You probably should contact Nitrado Support directly or do some searching in the forums in case someone else had already ask a specific game. IE: MC only available on PC, not XBox if I recall.
