Use of different types of communication
Noticed recently that the three generations use different methods of communication with the player. Owlks use slide shows/sight, Nomai use text/reading and Hearthians use audio recordings/hearing.
I thought that it was really interesting, I don't know if it was intentional or not but that level of attention to detail makes me love the game even more.
Maybe it's just logical that because we cannot translate Owlks text but we can with Nomai text and that we can understand our own race, that we have to use those mechanics.
