Wow there is a lot of thinqs I did't know (well I haven't yet X-Com: interceptor but I'm still searching for it [and if I get Apocalypse I will get this game to!]), , I really want know more about the other Aliens, the ones in war with the Sectoids.
and anybody know who was first? the Sectoid or the Aquatoid?
I'd go for sectoid. I believe the aquatoid was an adapted sectoid to underwater environments.
And I think aquatoids were the first ones; if I remember correctly, the sectoids from the UFO: Enemy Unknown were considered to be descendants of some aquatic race.
However, I personally think of X-Com: Terror from the Deep as more a fan fiction to UFO: Enemy Unknown than a consistent story part, so I don't really care

Nice ressurection but while we're here and discussing it... Aquatoids came first, that's where the webbing comes from. The Sectoids were the mutation of the Aquatoid gene allowing it to survive prolonged periods of time above water. Unlike the amphibious aquatoid however, the sectoid has been engineered in such a way that it cannot survive in an aquatic environment...

Also why not check out XCom : Colonisation over in the special projects forum. Won't kill you if you do, might kill you if you don't!
