Favorite quote so far?

Have You guessed already? It's too obvious, isn't it?

it's after establishing the colony on Elaadan (or however you spell the Krogan planet, haven't played in a while)

"I'm the Pathfinder rah bah!"

Ryder: "Hey Archon, don't blame your people for this one this clusterfuck is all on you!"

Ryder Sr.: "When your back is against the wall you can either climb it or use it!"

Not sure about the exact quote, but Drack and Vetra in the Nomad. Drack complaning over his getting old and asking Vetra: "You get tht?"

Vetra responding: "No, I don't get that and I certainly don't talk about it".

No worries!  I love Stargate so I'm always up for a good quote.  In fact, a lot of Andromeda's elements remind me of Stargate - more so than the original trilogy.  To me, that's absolutely fantastic and just more to love about the game.  

SOME BIG GAME SPOILERS TO FOLLOW:

I suppose broad strokes, the plots of the game are very similar as well especially to Atlantis.  A civilian run operation go to a different galaxy where they find advanced technology that only certain people can control (Sheppard with the ATA gene and Ryder with SAM).  The leader of the military operation is killed on the first mission (Colonel Sumner in Atlantis and Alec Ryder in Andromeda) by a hostile race of unknown aliens that utilize advanced biological weaponry (partially organic HIVE ships and life draining abilities by the Wraith, exaltation by the Kett).  A younger, cocky member has to step in as a leader of the exploration of the new galaxy (Sheppard and Ryder) and are forced to fight this new enemy at every turn.  They meet the locals of the galaxy and form a friendship and alliance, largely forged by the new leader - finding out these new allies were all part of an experiment by an extremely advanced race (humans in Pegasus Galaxy were brought there and "seeded" through the galaxy by the Ancients who created the Stargate's and Atlantis itself, the Angara were created and "seeded" through Heleus by the Jardaan who created the Remnant, Meridian and the terraforming network).  Despite being far outnumbered and at a technological disadvantage, the group from the Milky Way makes use of advanced weaponry and ships left behind to defeat their enemy (Sheppard and the Atlantis crew using Atlantis as a ship and using the drone weapons to defeat their enemies, Ryder using the Remnant technology to activate a fleet and defeat Archon)

It's actually pretty astonishing when I played through how many homages to Atlantis were in the game.  Frankly, so many of them, I suppose can be seen as Sci-fi tropes, but there are more than a few things that I think they took direct inspiration from Stargate.  Maybe that's part of the reason I love the game so much more than many others.

"So much violence " , from an Asari who developed Invasion as main power.

cracks me up every time.

huh so you waited that long to do coras loyalty mission?

Some of the banter is just so cool.

Liam: So... Do all Angara snore in their sleep or is it just you?
Jaal: Well, do all humans whimper in their sleep or is it just you?

Only twenty seconds long, but I love this brief conversation! Even while playing a professional/ logical Ryder, I always choose the emotional response for this part (among a few other parts throughout the game). Seriously, some of the game's dialogue is just so... special.

"Liam! Hold me!"
"I'M SAD I CAN'T PUNCH BOTH OF YOU."
