Time jump is a bad idea.
IMO 600+ year time jump is a bad idea. A big part of what makes ME universe so appealing to me is that it’s only like 100-150 years from our time and that is also what makes it stand out amongst other sci-fi franchises. I want to see a direct aftermath of the reaper war be it as Shepard or a new MC(although I’d prefer Shepard). I think it’s very easy to bring Shepard back even with a time jump because of the Lazarus project he is not a normal human and his longer life span can easily be explained using it. Having Andromeda being set in a completely different galaxy with new character was fine for me. I liked the game. But for Milky Way I want to see an aftermath.
