Are there too many unresolved plot points in this game ?

You can't honestly say that they have no long-term plans around these points. You're basing that assumption upon their lack of proper planning with the OT. It may have been true, then, but it's still a baseless assumption, in this case.

They already told us what the Scourge is, in broad strokes. It's the defining, unique feature of the cluster, with ties to the powerful species behind the scenes. I never expected a full reveal in the first game. Should we have?

We will likely learn about "Ark Quarian and friends" in the super-obvious DLC they advertised.

The kett are part of a larger, expansionist society from Andromeda. Did you need all of their mysteries revealed in one game? Our interactions with the Primus, and her closing scene, tell us that they're likely to return in future games.

We already know the purpose and origins of the remnant, in broad terms. Again, do we want all of the mysteries revealed in one game?

Is Ellen's cure a big deal? We don't even learn that this is on the table until late in the game. It's a cool side-story for the Ryders, if they return.



This leaves us with "Who's the benefactor and why was Jien killed?", and "Where are the Jardaan and their foes?", essentially. I see no real reason to suspect that BioWare hasn't carefully considered these questions, already. This game is full of improved, better approaches to old weaknesses. I doubt they're throwing 11th hour darts, this time, or scrawling pivotal story moments on napkins.
