So I sync'd the different languages in the ship part of the main game, just to have a "visual proof" that Japanese saves ~1 second over other languages and especially English (which is the slowest language) https://www.youtube.com/watch?v=9UiLAmxKeIk Otherwise I don't believe languages matter in any other part of the game when it comes to speedrunning purposes. On a side-note; I tested and recorded that on "variable framerate" settings, so capping your framerate to 30/60 *might* influence phonecall's duration a tad bit. PS: Put the video on 0.25x speed to clearly see the differences between versions
