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.
Not video, but many Asterix comics get released in Latin and regional dialects.
Also, I liked how in Enemy Mine they both learn each others language instead of the Alien just learning English.
