VentureBeat claims we're going to get a MET Remaster "Legendary Edition"

Unless during those thousands of cycles were every 50,000 years life was reset by the Reapers the Kett grew and expanded. Allowing them to take over large portions of the Andromeda Galaxy.  Having the Kett only active for the same length of time the Asari were in the Milky Way (2 or 3 thousands years give or take) is stupid given Andromeda has has literally billions of years for evolution and development of life.  So unless the Reapers were going between Andromeda and the Milky Way to harvest all life the Kett and countless other races would have developed and spread in that time frame. Given the Milky Way had advanced interstellar races before even the Dinosaurs walked on Earth.

And There is even a codex entry that talks about how vast the homeland of the Kett Empire is. How it covers many many star systems with many slave races under Kett control.

And this is the problem with Andromeda over the OT. It isn't organic and everything feels specifically constructed just so the Initiative can play the underdog. OT everyone is about the same tech level because they reverse engineer technology from Prothean artifacts and have a standing rule to share all new discoveries because of the potential advantage a single race can have if they horded it.  Andromeda everyone has the same level of technology because reasons. 

The Reapers methodically harvest all races of sufficient technological advancements sparing the younger races and leaving planets in a state that they can regenerate new life.  The Remnant build massive terraforming machines without any sort of back up system so they go hay wire and render planets uninhabitable for no reason other then to have the Initiative fail at first so Ryder can ride in and be a hero.

OT we learn the Protheans helped guide and modify early Asari because they viewed them as potential future joiners of their Empire and later as  the successors against the Reapers. Not to be out done the Jadaar one upped that by creating the Angara from the ground up like it is some dick measuring contest.

OT the galaxy is a big dangerous place and there have been several wide scale wars costing billions of lives for poking around places without exploring them first so literally every race has fleets of armed war ships to protect their colonies and for exploration in case they come into contact with a hostile alien force.  Andromeda is lol lets jump millions of light years and hundreds of years away from any support armed with only some small arms and a few shuttle craft for defense. Clearly the mountain of history and billions of corpses don't mean anything.   OH NO there are hostile aliens who don't like us and would have easily wiped us from existence 0.356 seconds after showing up if their leader didn't give a shit about us for plot related reasons.  How could anyone have known that there are other races out there that are hostile and might attack you for showing up in locations you don't know anything about?

OT fans complain about how silly it is the Cerberus magically gains all these tech advantages. Cue Ryder senior building a super powerful EDI level AI with spare parts in his garage while EDI at least needed Reaper tech.  Cue the Kett being mostly biologically focused in tech development with other technology seeming to be more imitative than innovative.  Cue the Archon being able to magically understand everything about AI and the connections despite there being no sign of VI or AI equivalent in any Kett tech. Because plot demands the Kett magically learn and master this technology.

Andromeda did have potential. But that potential has been knee capped by the first game that doubled down on the worst aspects of the OT with only a few of the peaks of the OT.
