It was explained why she looks different than the previous Altarian leaders.

The Torians are being turned into space burgers by the Drengin, and the Korx have been assimilated by the Krynn. Although the Torians might return in a DLC or expansion since they are mentioned in Major Civilizations Unaccounted For, unlike the Drath, Korath or Korx.

But, but, but...

I want my GREEN-skinned space babes!

The altarians are based off the races in elemental. There are a blue skinned sub-race of altarians. It is also possible for people to develop blue skin, so it is not far fetched that the leader is blue skinned. This has also been debated in depth in the dev journal introducing this leader.

Actually since we raising this anyway, the whole story of Altarian survival, against the looming Drengin conquest, i don't buy it. It amounts to magic, may as well have added dragons and the castle of Camelot into that back story; "Hello, Drengi, im the new, blue Altarian leader. Winter is coming! Dun-Dun-Dun" lol

Rewrite it. There could be any number of plausible explanations as to why they survived. Could be, that the last ditch effort of Altarian naval engineers payed off, they built a number of highly advanced vessels of war, tipping the balance of terror in their favor. Altarian core worlds the able to resist seemingly endless tide of Drengi onslaught, destroying two thirds of the Drengi armada. Some of those ships where also lost or damaged, but enough remained to deny any more loss of territory. The Your did not deploy their fleet during this effort, and simply observed Drengi losses. This unnerved Lord Konna, and ordered the remaining fleet back, settling an armistice. He was not about to loose all to the Your, having achieved so much. While Drengi public savored triumphant success, and the aristocracy delighted their guests with select Torrian meals (often the young, Torrian victims are "prepared", with "delicious dressing of eatable leafs, marinated with a thick layer of <Drengin> sauce"  and consumed while still being alive), Lord Konna remained alert. The Your where a worthy challenge in them self, but something bigger seemed to loom just over the horiszon. Or some other kind of story, i'm no writer.

I'm not saying anything against it since this is Brad's work from start to finish and I go by the lore he puts out. He made a fun game to begin with and I suspect that this would be a fun game to end with. I suspect that a DLC would be a leader pack and we may see other Altarian Leaders to appease the masses.

...this does bring up the issue of margaritas coming into play again...

I'd say it's rather the other way around. Sounds familiar? 

Nothing. It's still the case. Take a look at Rhonin's post.

Not really. At least not the way I understand it. Both games take place in the same universe: Elemental is Altaria, only in its distant past. 

No. If I did, my life wouldn't be as bad as it is.

There was no 29th February this year, because it's not a leap-year.

  There is nothing wrong with having blue aliens in the game, or any other color. That im asking for is consistency, while those blue ppl can be another kewl gal civ. Bottom line, i never ever had played none humans in Gal Civ 1 or 2. So for me its purely aesthetic, and lore related interest. To that end, outside of main campaign (and also Drengin, in the Dark Avatar expansion), i never liked vanilla Terrans, and always used a custom made human civilization (Argon Galactic Republic, as i named them). To that end, if Gal Civ 3, includes animated custom human avatar (and possibly a custom home world that we can assign to a custom race, rather then using generic ones), for my AGR faction, it would be dream came true for this game. 

  However, just cause i don't actually play none human, or even none AGR faction, i can still appreciate consistent lore, as well as diversity. I want Altarians to retain their human color, and those awesome tattoos, without a redesign of the species, to a new "brand".  

< PS: Argon Federation ( i twisted the name to Argon Galactic Republic) is not a name i came up with, and is a name for a civilization in X2-X3 Egosoft series, while Galactic Republic portion, is a tribute to Star Wars lore... >

How do you know that Argyria is the reason if they aren't even genetically compatible. (even after all this time in the 23# century. :/ )

DARCA.
