I spent forever in the citadel doing side missions, yesterday. So much backstory and little things I skipped during that first playthrough--combined with the amount of time that's passed since I got the game and, it's like a whole new game to me.
I bought the "Bring Down the Sky" dlc about a year ago but, never played it. I got the pinacle Station content last night. I loaded the game to my HDD, too. It's a 2007 game, but I found myself looking at the character's (especially Wrex) skin, lip movements, and mannerisms and thinking, "Wow. This is so amazing."
Currently, I'm taking my time, exploring various planets.
