Cora's Loyalty mission was ruined for me...

Well, let's see.  The race has the genetic components from exactly one species.  I don't claim to really understand what the father's of asari children bring to the table but it's not DNA (or what passes for that in non-human races).  That could account for similarities among the asari and even why many use facial markings - it's a way of distinguishing them.  I'm sure there's a real world more blase reason for them looking the same but here's an "in universe" type of solution.

I don't think they did a particularly good job on it, it seems too ...wide maybe?  puffy?

not sure how to put it, but they're off

ME1 : Enemies everywhere!
MEA : Dr Lexi everywhere!

I can guess where the five years work went to; environment, armor, vehicle and craft system. The rest took a back seat, very far back I'd say, for them to take the most convenient / easy route; clone the asari.

The thing about the OT was, that the asari all just looked rather generic. Everybody kinda looked that way and it was ok. The facial markings were very cool though and you could differentiate between them well.

What makes me feel really weird in Andromeda though, is that the "Lexi face" looks... How should I put it... Unique in the sense, that the face shouldn't be found everywhere.
Imagine if they had reused Mirandas face verywhere in the OT. She looks unique in her own way, not like an average npcs you forget in like 2 seconds. Her face had these special aspects, that made her feel very different from usual CC npcs and recognizable.

Lexi doesn't really look like an unimportant npc when you meet her for the first time, so it's really fucking weird starting to see her face literally everywhere. They are literal clones. Not even average cc-face npcs, they are literal clones.
How could they think that's a good idea is beyond me.

All the races look this generic in Andromeda imo. Some Turian npcs in the OT used to have some reeeally cool markings on their faces, but I almost never see that in Andromeda. The Salarians too.

Yeah true, there were never many heads for asari and I think a lot of them used Liara's model. They had a lot more variety in skin tones/textures, eye colours and markings though. Like the Turians and Salerians at least seem to have that still, not as good as in previous games but still there is some variety. The Asari have barely anything.

Anyway yeah, I don't think you can really get away with this anymore, reused faces with these kinds of detailed graphics is just more noticeable and annoying. It evben annoyed me in the Witcher Three, there were a few faces that kept popping up and that wasn't nearly half as bad as this, they didn't do it with important npcs.
