(2:55) Yeah I mean, if this is how we want to make our "silent protagonists" in future I am all for it.

I guess in the sense that the goal of a silent protagonist is often to allow the player to project their own personality into it, and the various story branches and dialogue choices in Mass Effect allow you the player to have a notable impact on Shepard's personality... sure, in that regard their roles are similar. But in comparison to any actual silent protagonist you could name there is vastly, vastly more to her character, both in terms of a personality and a well defined character arc. Considering how much dialogue they had to record to cater for all her story branches I think you could also argue she's the furthest possible thing from a silent protagonist
