I love these threads it shows how much some people put into the game.
but for me I can never choose anything but Destroy.
from an in game perspective what is our mission?
eliminate the reaper threat.
from an in game perspective the only thing we have to go on is the word of enemy (star child is responsible for the reapers)
control - every example of people trying to control the reapers backfires completely. your mission is to wipeout the threat not attempt to control it.
synthesis - in game without knowing what happens you cant be sure of what's going to happen, you stop the reapers at what cost? your there to save the galaxy not forcibly alter the DNA of every living thing without their permission plus the threats not eliminated the reapers still exist, from in game how do you know the threat is ended permanently if the enemy remains
Destroy - from in game the only logical choice, star child gives you omens about future threats and warns you about the loss of tech, but you destroy the reapers, your mission is to destroy this threat not mythical threats that may present themselves in the future.
the simple fact is from an in game perspective only one fact cannot be argued with without bringing in information that the PC could not have that is fact is as long as the reapers exist they are a threat.
and this is why I love that the ending was made hard, the geth are wiped out, EDI is gone (the head of the UN seeing he's a VI) the relays are damaged get a low enough score and the earth is wiped out.
the cost is high....but its tangible you tally the losses at worst you lose earth, the relays, EDI, Geth and your own life. you know those that survive will be completely safe and your no going to horribly mutate everything in the galaxy.
your job is to eliminate the threat this is the only option that can guarantee that from an in game perspective. Destroy is the only logical choice without meta gaming.
its the same issue as the rachni queen, you discover a creature who's species started a war, all indications are they are smart and violent, it makes no logical sense to release the creature the risks are far too great to take it at its word, you've known it for 30 seconds after battling through dozens of its offspring.
the collector base again a ship you don't understand, that controls peoples minds and builds baby reapers. why in gods name would you hand it to the most shady person in the galaxy? who trusted him through out ME2? anyone? no of course you didn't, we can tell he's just using us that he's up to no good hes given you no reason to trust him plus the risks it presents even if he's on the level? that base goes boom.
