Oh and Mordin is clearly the breakout character of ME2.
Yup, he was my favourite new character in ME2. I couldn't stop myself from laughing whenever he started speaking at a really fast pace. And when I got him to do his "Gilbert and Sullivan" routine, I thought that was the funniest part of the whole game.
And if we're comparing romances here... the first time was a MaleShep who did Liara in ME1 and then Miranda in 2. Second run though that I just completed the other day was a FemShep with Kaiden in 1 and Garrus in 2.
Plus I managed to get the whole team through the suicide mission intact this time, unlike the first time.
