The problem I had is that none of those 3 choices at the end were in line of what my Shepard would have chose. My Shepard was sympathetic toward the Geth and believed every race deserved a chance so he wouldn't have done the Paragon route of destroying all sentient life which included the Geth, EDI, and I dunno, some advanced ipads maybe. He wouldn't have gone the Renegade route by controlling them because he was always against that and never believed it could work. And then I guess the 3rd option only unlocks if you meet certain criteria which I met but I still decided against it because that ending wouldn't have made much sense either.
It's hard to imagine any one person's Shepard to be comfortable with one of the three choices at the end, to be honest. Actually, doesn't it seem like the Paragon and Renegade endings should be switched here? If you go full Paragon, doesn't it make more sense to choose the Renegade ending and control the reapers and let every species live? If you go full Renegade, doesn't it make more sense if you choose the Paragon ending by wiping out synthetic life (which you presumably didn't enjoy in the first place if you were a Renegade) and allowing the advanced species to prosper?
Or do I have the endings backwards in the first place? Because here is a video that shows all of the endings. The top (Red) are destroy while the middle (Blue) are control. I was always under the impression that blue was Paragon/destroy and Red was Renegade/control.
I chose Paragon/destroy (at least I thought I did) and ended up with a blue ending.
