New galaxy, only 2 new aliens/races?

Because it is only a single cluster out of the entire Andromeda Galaxy. Mass Effect introduced us to the entire Milky Way and the races that lived there.

Are the Remnant even technically a race? Also, don't forget the Angara.

And just how many sentient species does the Local Cluster have in the Mass Effect Trilogy?

The answer may surprise you.

They're a faction of sorts.

A whole game dedicated to two races ane yet the writing and story is so badz I care less for them than a single hanar In mass effect 1

I think many seem to be forgetting that the Heleus Cluster appears to have been a dead cluster before the Jardaan arrived. What I mean by a "dead cluster" is the Jardaan allegedly went to the cluster to terraform planets and restore (or create) them. Even the Angara were created by the Jardaan, implying there were no other species in the Heleus Cluster.

It's silly to compare the Heleus Cluster to others because it has been built by artificial means, rather than natural evolution. It should also be noted that the Kett have performed exaltation on over 1000 species in the Andromeda galaxy. Even if there were other species to see, it's likely the Kett would have wiped many of them out due to their never ending quest for perfection and dominance.

I don't think they have Mass relays. No, there most certainly isn't any Mass relay technology in Andromeda. So travelling outside the Helios cluster might not be plausible for the species inside the cluster. The Helious is just a small part of a big galaxy.







Without Mass relays it's not possible to jump across clusters for a human lifetime, even with FTL speeds. If you would for example travel at the speed of light across the length of the Milky Way, it would take over 100,000 years.

So the reason you see only 2 species in what seems to be a small, local war between the two is because without having access to jump gates, it's not possible to further explore outer reaches of the Helios cluster, as there might be a lot of empty space between the nearest other cluster, making it impossible to travel back and forth within a lifetime to see what's out there. That is without a technology like Mass relay, of course, which makes it possible to jump across Milky Way instantly (works pretty much like a worm hole would).

And the thing is, that even most of the Milky Way is not explored as the current Mass relays that we have don't connect to all the destinations. It took 600 years in standard FTL travel for them to reach Andromeda, which is actually extremely fast FTL, considering it would take 100,000 years to just cross the galaxy at base light speed.

The data wasn't that old. They had a geth built FTL telescope that cut down the lag significantly. They don't specify how much it cut the lag by but it's implied that their data was only a few hundred years out of date.

actually since the kett are multiple species mixed into one you have go thousands in the archon alone. lol. Also the remnants are more like protheans given they seemed to be running from something or scared of it. Whatever they were scared of could be like the reapers I guess.

Was it? Early on it's stated that the remnant structures weren't on their scans and must have been built after they left the Milky Way. This implies that the golden world were golden before the Jardaan arrived. 

I think the Archon, at one point, says that he's the something, something of a thousand races, species or something. Granted, it may been boasting on his part since he says it during the final battle and so it may not be an accurate number but then we also don't know how long the Kett, in some form or another, have been around.

Actually, if I heard right, the Angarans said the Kett "arrived" in the cluster, or their boss did, so they're not from there either, so it's technically only one new sentient race. But don't forget all the new wildlife, they count right?
