In general, I really enjoyed the missions in Overlord. While I enjoyed the Kasumi DLC, I wish that there were two missions (a recruitment mission, as well as her loyalty mission) instead of just her loyalty mission, especially since it wasn't free like Zaeed's. I'm definitely looking forward to the Lair of the Shadow Broker DLC (my female Shepard had a relationship with Liara in the first game), so it's nice that Bioware is going to let you expand on that relationship.
Even though I've played ME and ME 2 numerous times, I'm really excited for the PS3 version of ME 2, largely because I'm interested in seeing how they incorporate the prologue/introduction to compensate for no ME 1 (and it will be a good opportunity to create another Shepard without having to play ME 1 again).
