I was wondering if other people do what I do, which is create (and keep) more than one Shep in ME1 so that you can carry them through to ME2 & 3 without sacrificing the internal logic of each Shep's character?
So for example, I have 5 Sheps in total, 4 female and 1 male. That way I can experience every romance that I want to (not every romance in the game, just the ones I like). My engineer romances Kaidan in ME1, stays loyal in ME2, Kaidan again in ME3. My adept does the same, but with Ash. My soldier does the same with Liara. My vanguard romances no one in ME1, and Garrus in 2 & 3. My infiltrator romances no one in ME1, Jacob in 2, and Sam in 3.
I also like this method as it means I've got all but one of the classes on the go, plus they all have a different mix of background. Anyone else do something similar? Maybe I'm just weird!
