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.

For music, you should listen to Sigur Ros. All their lyrics are in a made up language.
Many of their songs are in Icelandic actually, and a couple in English.
Oh shit, really?? My life has been a lie! Thanks for correcting me!
