I tried Tempo and it seems to do the job well!
There’s some features I wish were present, like selecting multiple songs, but the feature list is quite good regardless
When you’ve clicked on the show and its showing you all the seasons/episodes you have, click on the settings (three dots) and select “Identify”
It’ll bring up a menu where you can input the name of the show, or its iMDb code, or a few other identifiers and it’ll show the matches it can find. From there you can select the correct show and it’ll populate the metadata accordingly
Haven’t played Gostwire Tokyo, so I’m not sure exactly how it plays, but you might also enjoy the Witcher 3 and Middle-Earth Shadow of Mordor/War. They both have good combat systems and skill trees (although they work quite differently), as well as an open explorable world. I’ve played Shadow of Mordor (Steam version), so I know that works fine on Linux
Lemuroid emulates most handhelds, and works pretty well in my experience (S9, to give an idea of performance)
Will this work even if the drives are different sizes?
