Destroier asked "It's just me or this Ancients race are the ones from Stargate SG-1?"
Not likely, as much material for the Traveller RPG comes from 1978 or so. There are diferences between the Asgard and the Ancients, but telling you them here might spoil your SG-1 viewing or your Traveller play.
The Ancients were but one of many things to discover and explore in the Traveller universe. One thing that set Traveller apart was the really cool back story, and the Travellers News Service. In the Journal of the Travellers Aid Society, there would be these little news briefs of happenings in other parts of the Imperium. To me, it gave the impression that the hardy band of adventurers that I was a part of was just one small bit of much larger goings on.
MT2 captures much of the spirit of the original RPG, and is loads of fun.
Try the game, you'll probably like it. If you want more, the paper version is in reprint, and MT2 is a fine character generator for the paper version!
Cheers!
