I thought of DA:I recently and how I don't think Bioware really had the power to create a player-protagonist being in charge of the game's central organization but then I thought it would've been cool to have been some sub-guy of the Inquisition working for it, like a spy for example and somehow you'd be the most relateable and interesting character within the organization without being the leader or anything, and I'm thinking, I would really like that for Andromeda. It's probably not going to happen given the premise we've heard about but I'd love to be someone relatively unremarkable who becomes the hero, kinda like DA:O, but in Mass Effect.
It would be much more interesting than the "Player is the most important and powerful character in the story" circlejerk.
Honestly, I didn't feel like I was "in charge" of anything in DAI. It seemed as is Josephine, Cullen, and Leliana were running the show with the occasional shout out from Cassandra. If anything, I felt like a figure head with a worthless title and a silly mark I used to close rifts. That was about it. The war table never made me feel as if I was commanding an army. The throne mechanic was underused and was ultimately just window dressing. Anyways, I'm getting off on a tangent about my issues with DAI, and there are many.
Well, Shepard is the "most important and powerful character in the story," so that title has already been taken. BioWare also alluded that the new protagonist is going to be a rookie of sorts, but a very talented and skilled rookie. Whatever organization we happen to be affiliated with, I think we are going to start off as a low rank and move our way up the totem pole. From what I can gather, we are just going to be an explorer, and as the game progress, likely our influence and authority will grow as well.
