The leviathans the key to the future of mass effect?

i could see the idea of acquiring reaper tech being a focus point as reaper tech is more powerful than anything in the milky way species. this assuming it happens in the milky way it wouldnt work in Andromeda.  

Griffith82 it would also start bring in issues of cannon that star wars got hit with which lets be honest no one wants that mess in Mass effect. also the reason why i choose the leviathans is because they arent the reapers. they operate differently and act differently. And as i think personally that they should continue mass effect in andromeda for the fact it would be easier to write and avoid the mess ME3 caused, really using the leviathans as a plot device somehow is one of the few ways that we can connect the two galaxies together without doing alot of explaining and reconing. are their other options sure there but using the leviathans is in my view one of the most versatile options.

Why do they need to finish off the Kett? im actually really curious on why

If we get a MW sequel, one that I would really welcome. I would also have the Leviathans as the main enemy.
However a couple of conditions must apply for this to be successful IMO

1)All relevant info Shepard got was lost after the war and we get to find them and face them again with a new protagonist who abolutely know nothing about them.

2)Leviathans operates in a different level than the Reapers, they are not enough nor have the same strenght of the Reapers to conquer the galaxy, therfore their threat must operate through deceit, shadow agents and manipulation instead of direct force. In theory the galaxy should have no problem once the Leviathans are perceived as threat to annihilate them however they operate in such a way that nobody get to notice them.

3)Their indoctrination should be more subtle and evolved than those of the Reapers, people being indoctrinated by them should retain most of their capabilities and do not become husks or slaves, instead manipulated agents who do the Leviathan agenda without knowing thinking they operate on their own free will. Like TIM used to think.

4) The galaxy is broken into factions and decayed into a more primitive age, chaos and piracy are a serious threat and the protagonist must help shape the new MW order and oppose the Leviathans meddling that are trying to shape the post-war galaxy their own way.

5) Consequence of 2),3),4) means that a greater emphasis should be put on politics, intrigue and investigations and less on open warfare. I could imagine the protagonist being some sort of secret agent trying to find links of the Leviathan conspiracy inside the MW galaxy.

Just some ideas

I'm not bothered if anything Reaper or Leviathan returns, I just don't want a (multi game!) main arc about either, while balanced with giving both the weight they'd otherwise deserve. A difficult task that I can respect wasn't even slightly attempted in MEA.

But really I'm really up for them being things that existed/exist/will exist. Just do it smart, unlike, uh, say, Collectors in ME3(?; MP? Arena? IDK? Black Ark? IDK?????).

Sorry, I also meant I didn't really want a single game arc about them either. I guess I'd accept it over multi game.

Perhaps Leviathan as the face villains before something very non-Reaper/Leviathan comes up as the larger danger, or something.

I don't either.

I do think that the Leviathans theoretically could offer something more than 'Reapers'. They had a long history and we only know the gist of their near extinction.

True. There could be potential there. I'd still rather Andromeda get finished though.

i have faith in bioware to make them differently than the reapers if they are given enough time to write a decent story
