By everyone I mean everyone but you, because I know if you died the save wouldn't carry over. Because I just beat ME3 with a save where everyone lived plus all the DLC. So is Garrus and Miranda not even in it?

I'm pretty sure the worst ending where Shepard lives in ME2 still had two other characters surviving.

Also Garrus and Tali are party members. What happens if they died? Did someone replace them?

Don't know, but worst case scenario: (minor, minor spoiler?)

So I guess that even if they aren't replaced, you'd always have a minimum of 2. My ME3 save is fairly "perfect" though, so no first hand information. I can imagine things being much more dire though.

Liara and Vega are not part of the suicide mission, so you'd always have those?

@ttocs: Yeah, this whole thing kind of makes me a bit interested in coming back with a "worst case" save... wonder how bad/hard it would get.

Then again, I don't really want to know 'till earliest when I've finished my first ME3 play-through. :)

They're replaced in the story, but not in your party. Party members from 2 that are required in the story (Mordin, Legion) are replaced, the rest either has a minor replacement or don't appear at all.

You'll always have at least three people up until the endgame even if you fuck up your ME2 save and don't have From Ashes:

Liara, EDI and Vega - they fill the "one biotic, one engineer, one soldier" quota and have plot armor until the ending. Ashley/Kaidan you can leave as a War Asset or kill off, Garrus and Tali you can also kick off if they appear.
