The hell did they do to the Protheans? xD
They got retconned to look like shrunken Collectors. I know that makes sense now, but... did they have to sound like Zulu warriors? xD
This has always been my fear for Mass Effect. I'm adoring it, really, and it's actually surprising me with how well it's handling the whole invasion plot arc, which I was always worried about. But taking away the mystery and the unknown element of something that was built upon and relies on that secrecy kind of destroys it in my eyes.
I've seen the Prothean's end, I've talked to one, I've heard his account, digested his emotions on it
I can compare this to going out for coffee with the last Atlantean, who has 6 arms, a flat face, and waddles on a rounded bottom half, having a long, detailed discussion about how Atlantis was just a port town which went under from a tidal wave. A good story, bro, but the specifics of your culture and your unique biology could never stack up to the story behind your peoples loss. I'm sure there's a perfectly good reason Evolution granted you one ass like appendage for travelling, but I didn't want to know that Atlanteans travel on their asses, thank you.
