I decided to download a savegame editor rather than replay me1 and 2 because I fairly recently replayed them both (around the release of ME3).
I didn't really change much with the editor but I fleshed out my shepard a bit more, activating flags for some side quests that I missed and stuff.
So yeah, playing ME3 now.
I really like how the renegade conversation choices don't make me feel like a complete starfish to people I don't want to be a complete starfish to.
