With machine translation getting stronger (although they will always be inferior to being actually translated by an expert), the only obstacle is actually finding someone to hack the game, rip the text for the translator and properly insert the translated text into a patch. Where do translator find such people and how do they convince them to work on the game? Do they pay them, are they friends or acquaintances with them or is it hoping that they are interested in the game and turn it into a passion project?
