User blog comment:RayShepp654/How to defeat the Reapers Theories/@comment-217683-20101028230139

I don't really have a fleshed-out theory, but (and I hope you don't mind me using my post more to nit-pick your theory... if you do, lemme know and I'll keep my yap shut in the future! :P ) I'm not too keen on the idea of going through all the effort just to have a textbook deus ex machina ending, such as the proposed "going to another galaxy, where the locals show us how to stop the Reapers". That just doesn't sound that satisfying to me. I'd much rather have the defeat of the Reapers be a strictly Milky Way races thing.

I'd also like to point out that, contrary to the post (sorry... again, I'm a nit-picker!), we did not witness "at the end of ME1 how it took the whole Systems Alliance fleet" to destroy one Reaper. What we saw there was part of one component of the Alliance Fleet (the Fifth Fleet) taking down a Reaper. Not the entire Alliance fleet, not by a long shot. There weren't even any Alliance dreadnoughts or carriers present, just cruisers, frigates, and fighters. The entire Alliance fleet would have been much larger (as even before the First Contact War the Alliance Navy had at least 200 ships) and would have included much more powerful ships than we saw at the end of Mass Effect. As such, I do think you are underestimating the ability of the Milky Way races to fight the Reapers.
