So, Im slowly getting back to ME2 after my initial playthrough due to major setbacks caused by school and other games, and Im playing on Insanity using my Soldier from playthrough 1 that I imported from the first game. Now insanity is hard. Ive beaten Gears on Insane and MW2 on Veteran with only mild setbacks, but the mechs on Freedom's Progress almost led me to put down the controller.  
   
So Id rather just blow through the campaign as quick as possible, without doing loyalty quests because on insane the AI is useless anyways. The only setback is that Im fearful the choices and decisions made in my first playthrough wont carry over to ME3. Rather the 2nd playthroughs decisions will. I really don't want to lose the character Ive developed from the beginning of ME, so Ive been going through my 2nd with the same decisions, or the same as best I can remember. 
 
My question is... will my choices from my 1st playthrough carry over even if I finish my 2nd playthrough??? Will they both carry over??? PLease help guys. Thanks.

If the import process from ME2 to ME3 works the same way as importing from ME1 to ME2, than you will have a choice to pick between your first playthrough or your second playthrough.

Thanks for clearing that up. I wasn't sure how the import process had worked in that situation, for I had never had a second playthrough.
