So I just finished Mass Effect 3 and I'm not even sure what just happened.....lol
My overall Galactic Readiness was at 89%, not sure what my EMS was. I think I was still around the 3600 mark but I forgot to check before heading to Earth. I probably should have paid attention to that more during this playthrough. I'll be playing through the game again, I'll make sure to try to get EMS up higher.
At the end, I decided to go the Synthesis route:
What endings did everyone else get?The third solution is SYNTHESIS. You can add your energy to the Crucible's. Everything you are will be absorbed, and then sent out. The chain reaction will combine all synthetic and organic life into a new framework, a new DNA. The cycle will end. Synthesis is the final evolution of life.
I can across this guide after I beat the game that describes all the endings.
