Is that "Word of God"? If so, that's pretty stupid given that the Geth last I checked don't really even want Rannoch and the other Quarian worlds
It's not so much 'Word of God' as how strong in metaphor it is when played out in Mass Effect 3's Legion storyline. I mean at the time I didn't think Israel v. Palestine but if told, there are some strong resemblances and parallels or with general slavery-revolution type of storylines.
It just seemed awkward to me as a storyline overall and this is despite me thinking that Legion was a very likable character in a game series that had lots of interesting and likable characters. It's been so long since I played it, but the Geth backstory just didn't seem to gel with how the Geth were presented right up to that point. It's really hard to engage in 'restrained' or 'inadvertent' near genocide of a people like the Geth did with the Quarians but that's how
Mass Effect 3 tried to lay it out as.
They just killed all of the Quarians until they left and it just so happened all of the pro-Geth Quarians somehow died in the conflict. And while the Geth are considered a threat to all of civilized space and extremely xenophobic and own swaths of space, they're not expansionistic or militaristic until the Reapers made them bad or something.
