(looks like this is the first thread in this forum)
Most of my choices had been predetermined before the playthrough started, but this one I wasn't sure on until a little before the derelict reaper mission. It was a hard call. Without meta-gaming, the decision made sense. There would likely be a greater payoff from studying the geth than questioning it; especially without the heretic insight. That's not why I did it though.
So why did I sell it? For similar reasons to why I killed Wrex on Virmire. I did not want my Shepard to develop sympathy/become an apologist for the geth, which to an extent, inevitably occurs if you recruit him.
My gut instinct says, in the long term, synthetics like the geth are a big threat to organics as Javik/the catalyst state. But emotional appeal keeps me from turning on Legion if recruited; the same way I've never been able to sabotage the genophage cure with Wrex alive. I believe the genophage is a necessary evil, yet I cannot betray him. And if I go against Wrex by destroying Maelon's data and no longer being his friend, he isn't angry. He is wounded, which is even worse. It's a situation I want to avoid.
And if you continue wanting the geth destroyed despite recruiting Legion and knowledge of the heretics, you come across as very cold, almost a traitor, which ruins the enjoyment.
So I played ME3 with an intentionally ignorant Shepard regarding the geth/heretic situation, hating those machines for their past bloodshed like the attack on the Citadel, and unapologetic for them; including the geth killing any organic who ever entered the Perseus Veil (peaceful intentions or otherwise).
The thing is, I like Legion. It's a cool character with amusing conversations, an unconventional personality, and a fun loyalty mission. Plus, it looks bad-ass holding that Widow sniper rifle that only potentially Shepard can otherwise use.
Has anyone done something like this for role-playing reasons?
