Oh, right, I forgot that not everyone takes the same assumptions as I did when I made my Mass Effect RP a while back. ME3's ending was, well, terrible, as most people agree. Last time I made one, it ended up being a sort of an alternate universe RP where the catalyst's "choices" were merely attempts at indoctrination. Shepard saw through it and activated the crucible, destroying solely the reapers. 

If I had to give a recommendation I would say that an alternate universe of that nature would provide for a better story overall. They attempted an unnecessary twist ending, introducing a few Deus Ex Machina divices and changed the entire tone and goal of the plot in the last ten minutes.
