This was the same thing Bioware did with Mass Effect for a while, focus on the characters versus the world. We all know how much ME2 and 3 diverted from the formula set in the first game too.
But I mean in Mass Effect, Shepard is not the star. Shepard is purely reactive in terms of what happens and you mostly choose between different flavors of "this is bad" and "we've got to stop them". The star of Mass Effect is the rest of the Normandy crew, and the galaxy itself. Don't advertise Mass Effect by telling us how great Shepard is, since Shepard is pretty much just a cipher. The star of Mass Effect, if there is one, is probably Garrus.
Probably a majority of the time in video games, the protagonist is the least interesting of all the major characters.
