I absolutely loved me2, I was about 20 hours into me3 when I realized I missed the chance to be with liara, I had to start over (i'm doing an insanity run), nothing will stand in the way between femshep and liara!!
The game is so damn good, I stopped just after the citadel attack. I was an infiltrator on hardcore mode and it was getting too easy, so I decided to start over.
