For Mass effect 4 could you go to a different galaxy like Andromeda or the Triangulum thorough the use of worm holes? Or have a main character from those galaxies ( kind of like a human)? Maybe the reapers were created by people who came from one of the galaxies in order to have intergalactic war with the other? There could be like a super reapers who uses stars for energy as one of the main antagonists for one of the games. There are really a lot of possibilities that this series can go with, im excited to see what happens.

Where do you go to post ideas? I was thinking maybe they could talk about a different universe like the main character coming from a different universe like andromeda galaxy.
