Ok, this is a slightly weird one. I finished ME2 a few days ago. I've just started ME3 and imported my character. All is well. However, I've noticed that, post ME2 ending, my Shepard is level 29. I'd kinda like to go back to ME2, do a couple of side missions and get that level 30 acheivement while I can. What's the process for going back to ME2 play through 2 with a character that has already been imported to ME3? Is this likely to fuck anything up? Or are they viewed as different saves between games?
