I'm pretty sure the blame for the ending("s") falls on the writers. Or, writer, in this case, as only one person worked on the ending: Mac Walters.
Hudson harped on about how different the endings were, how every story wold be different, how your choices matter.
He deserves blame too, hell some may consider his words false advertising.
I don't understand how you people...
Spoiler can choose the geth over the guarians. They are software! Even if it is are intelligent and self-aware, they still don't even exist physcially, only the platforms they run on. And remember, "never trust a computer you can't throw trough a window". Can you trow a Geth Dreadnought trough a window? Can you?


And ?
Spoiler Woop de doo, one is organic. They act more agresively (and stupidly) therefore they are in my eyes, inferior. Would you save a very agressive group, or the less violent, more or less innocent (acting mostly out of defense) one ?
How is a synthetic inteligence, worth less than the organic one ? Our brains are just made differently, and we exit becuase of evoloution. That dosent make us worth more.
Logicly, I would choose to save the less troublesome, more peaceful group.
Emotionaly, I choose the more innocent group.
Why wouldnt I choose them ?
