That would be great. I would love to have no backstory woven into the narrative. I want my characters to have a blank slate.
I disagree.
It's not a surprise. I've been assuming the worst(aka this) for months, but holding out a little hope. Now that little hope is gone.
And with no narrative people start screaming the way they did about DAI. Plus this means they can tell a more personal story, which to me, is appropo due to the fact that this kind of thing does have a personal angle. Leaving your old life behind, not knowing what happened, the uncertainty of the future.
There are eight bipedal races in the ME galaxy outside of humans. Of them only three have human like features: Asari, Drell, and Batarian.
Quarians don't count considering if this is pre ME3 ending they aren't leaving their suits. The volus aren't all that suitable as PCs. And then you have the Krogan, Salarians and Turians. I can't imagine that those three would be anything but resource sinks due to the requirements for customization.
So then we're back to the Asari, Drell, and Batarians, which will cause people to scream since why not have Turians, Krogan and Salarians.
