I beat it as well....Just a few hours ago.
34 hours, completed probably 95% of all available quests/scanning areas. Did not upgrade all weapons as I didn't need them (upgraded just about everything else). Got 45/51 achievements on my first runthrough. Achievements are a lot easier.
I had sex with Tali, of course. What ME2 player hasn't picked her for the first option?
I do have a question for someone that can answer it:
How do you get all people to survive the suicide mission? That is the only achievement I failed at on my runthrough (sans class-specific powers). I had one guy die on the Collector homeworld due to getting nailed with a rocket when the door closes. I assume that its because I picked the wrong person?
Overall, fantastic game. I did not like the 'twist' at the end. Compared to ME1, it was a big letdown. Kind of stupid and did not make sense vs. Mass Effect 1. However, lead-in for Mass Effect 3 was incredible. Only 2 more years!
Back from the dead, I'm afraid.
