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.
Poor entry here, but star wars knights of the old Republic did this for the aliens to save disk space on dialogue. The subtitles come up fine, because your character can speak all the languages, but the aliens have like 4 voice lines each they just repeat.
