You know how in fantasy worlds, its all english? Kinda breaks the immersion a bit. I wanna find something where they make it as realistic as possible, and make everything in a fictional language, basically using subtitles as the main way to understand the plot.
Star Trek and Game of Thrones have some lines in their fictional languages (Vulcan and Klingon for Star Trek, High Valyerian for Game of Thrones).
The games Out There and No Man’s Sky feature a mechanic where aliens talk in a completely unknown language, but as you gradually learn the language, the subtitles gradually become more and more English.
