Mass Effect.... like every other BioWare game, DO EVERYTHING, TALK TO EVERYONE, GO EVERYWHERE.
For me, the Virmire choice was tactical rather than personal. Ash was guarding the mission critical nuke and Kaidan was doing some random yotz in the comms tower. I think you can guess who got saved. Everyone thought I was awesome and everyone else lived. Except the bad guys. They got minced good and proper.
I romanced Liara, obviously, but went after Miranda in ME2 because, well, dayum. Plus, it's a suicide mission - who comes back from those? Also, seducing the boss's 2iC got her on side. But, back in the Lair... it was back to my favourite blue space girl, forevs. But.... breaking Miranda's heart in ME3 was truly painful to watch.
But Garrus... he's Big G. He's The Dude Of Dudes. And don't let anyone tell you otherwise.
Did someone say glaive?

This is the ultimate weapon!
Does anyone here even know what movie I'm referencing? or love it as much as I do?
Krull is ace. I have the DVD. I love the soundtrack. It's ridiculously, campily brilliant. And Bernard Breslaw as the cyclops. Cool.
Then it isnt a weapon but a YOYO!
Ya Lose Stinky!
Didn't the yo-yo start out as a weapon? Or is that a common misconception?
