Are you looking for a "setting inclusive" game, or are you essentially wanting to play Mass Effect the RPG?
If all you want is rules, I'll throw out d20 Future as a pretty good alternative. It comes with the old Star*Drive setting pretty heavily interwoven into the assumptions, but that's a pretty generic system in terms of space opera. You could easily use the rules to run a Traveller conversion, or pretty much any space opera.
I've always been a fan of Traveller too, and I like using their sector mapping tools from my old copy of MegaTraveller, with the hexadecimal system descriptions and whatnot. I've got a homebrewed sector all ready to go, but I've never run it. It's fairly system neutral, so I tend to gravitate towards more neutral systems.
GURPS, if you like it, has both the Traveller setting and their GURPS Space setting, which is really very similar.
