Played the first one, picked the game up Saturday and I'm in love with the game.
I only just got to Omega and picked up the Salarian. I imported my ME1 character. Soldier, lvl 42, saved Ashley, screwed Liara, saved Rachni Queen.
I'm actually looking forward to playing this game multiple times, not something I do often unless there is a lot of replayability and I can see this is going to be insanely replayable with the number of different decisions and having past judgement in ME1 attributing to the game initially.
