Andromeda Character You Would Have Over OT Character

Default Sara for Liara is pretty good, but if we're doing that, I want Default Scott for Jacob. Although him going with Cerberus would be a bit odd, unless the Ryder plot is kinda the same and he was shut out of good jobs in the Alliance because of his dad and...hm. Look, I just really like Scott. Also, Lexi! Chakwas is fine, but I'll take Lexi any day.

Maybe Peebee for Ashley, that would be pretty interesting. Keri over literally all the other reporters, Suvi over both our yeoman. The PTB of Andromeda are also way cooler than any of the Council. Other than that, the MET crew is vastly superior - mostly by virtue of having three games of development under their belts, partly by virtue of not being so annoying. Nobody jettisoned me in my own escape pod, nobody sniped at their squadmate across the entirety of a planet, I got to actually yell at idiots being idiots...So I wouldn't really swap any of them out.

From MET > MEA I would probably take Jack over Sloane - pirate queen - and Tali over Vetra. If I have to deal with parental issues again, I'd rather it not be coupled with an annoying kid sister you never shut up about, and I like having a quarian on my crew. Joker for Gil, though I guess that would technically kick both him and Kallo off the ship. Ah well, there must be plenty of other engineers on the Nexus who won't change things about my ship mid-flight.

I would replace:
Ashley with Cora,
Wrex with Drack (I don't think they're that much alike),
Kelly with Suvi,
Jack with Sloane
and Jacob... well, I would just airlock him, no need for a replacement.

Replace Ashley with Cora

I'd definitely take PeeBee over Liara and Liam over both Kaiden and Jacob.
