Lol, talk about shades of the past......
This was argued and talked about extensively to the Nth degree on the old Bioware boards. Like someone said, it is told as the difference between a controlled release and a catastrophic release. But hey, you want to talk about bad writing......I can go there......
1) Destroy ending(high readiness)....everyone doesn't die in space ships and planets as their tech implodes, BUT somehow all Reapers and advanced AI do......so somehow an energy wave can distinguish between the 0101 of a Ship reactor core control center and the 0101 of say the Geth....I could see Edi dying, because she was part Reaper tech, but how does an energy wave tell the difference between software programs?? Remember the Geth die....which are SOFTWARE, as repeatedly told to us.....Geth in one ending were actually helping the Quarians with their immune system by inhabiting their bio-suits and simulating sicknesses to stimulate the immune system of the Quarians, so Geth can survive in Quarian Bio-suites which says to me, they don't require that much processing power to run a Geth.....yet they die???? How energy wave know the difference between a Geth in a Bio-Suit and a program to regulate oxygen for the Quarian??
2) Why didn't Harby just shoot the Normandy down???
3) Synthesis ending......how does an energy wave use Human DNA to decide how to mate tech and organic on a planet across the Galaxy that probably doesn't even have anything close to Human DNA.....examples closer....Turian, Quarian(dextro based).......what about Prothean(4 strand dna)??? Where does the tech or organic matter come from?? How does it tell the difference between a toaster and a Geth??....Heck, Geth are SOFTWARE...the machines running around are simply platforms they can move into(think mobile homes for programs)....so how does a hardware platform having organic parts really solve anything.....ok, your nice travel trailer now has living tissue.....does it change you at all when you use it to go camping....or just gross you out??? Remember Geth are SOFTWARE by lore, as repeatedly told to us..... How does mother in Synthesis give her child electronic components in the womb??? Are animals now part of the collective mind?? How does that effect natural selection, wildlife.... What maintains the tech part of people's bodies??Can it break?? Who designed it??
4) Why didn't StarChild just open the Citadel relay for Harbinger??
5) How did people who didn't even know Starchild and the parts of the Citadel he inhabits existed, manage to create a machine to use it.....aka Crucible??
You see, they hand waved most of these points and said just because we said so...so why would a little hiccup about relay explosions ever register as an issue...???
We went from a SciFi space opera to a "Godmode" we say so in about 15 minutes at the end of the game.....so just wave your hand and poof it is all better now...
