Andromeda - Where is everyone else?

Well, it was because you speculated without giving any reason why? A hypothesis is based on an observation in the universe. In the universe of ME, there are many alien races in the milky way, that is an observation. So you can hypothesise there might be many races in andromeda. 
I was conversing with you because you just made a statement about there being less races but your reasoning was not based on any observation whatsoever in the universe of the game. Sorry Im a scientist, so my way of thinking has to be based on something, even something unlikely. Its not scientific just to make a random statement and then don't give your opinion on an observation as to why. Granted, it is possible there might be less races in andromeda, but why would the writers write that? 

My argument was that you are basing your observation on the real universe when talking about a component of a fictional universe. That observation doesn't correlate because the ME universe is another universe. Based on the observation of the fictional ME universe, there are a lot of races in existence, why then would the writers write a galaxy with less species in it when its twice the size of the milky way? This is not an arbitrary observation. Where is the observation in the ME universe to support your hypothesis? 
Also your point about life in our universe is a separate argument. In this second argument, you discuss that life has existed for billions of years which is true. But that we don't have evidence is alien life yet which is also true. 
I would counter in this second argument that you do not recognize the extreme limitations when coming to that conclusion. Humans have only been around for a few thousand years and we have only looked for alien life about 100 light years around earth only for the past 50 years using a limited technique of radio signals. That doesn't definetively mean there are no aliens, only that we have not met them yet if there are aliens. Which for something as big as the universe, would be almost impossible. 
Again I use my analogy of looking at the corner of a room and concluding because there is no one standing in that corner, that there is no sentient life on earth.  
Based on the size of the galaxy alone and also that the building blocks of life such as amino acids are created on asteroids. Also that we, humans are made up of the most common elements in the universe and other variables, it approaches impossibility that we are special and alone in the universe if we use methematics.
Countering someones argument is not berating them. Its how discussions are made.
Would the writers really make a game with only 3 races in it that are new?

... and your observation doesn't correlate any better than mine... since Reapers don't exist in Andromeda and Andromeda is millions of LY away from the ME Milky Way with life developing in accordance with whatever unknown conditions exist in Andromeda.  The development and conditions of Andromeda will be whatever Bioware writers decide it to be.  You can like or lump it.

We havent looked very far and we dont have the capability to look very far. We can barely detect planets around other stars, a while back even this was impossible.  We need better equipment, way better.

And SETI, pure crapshoot, they even admitted it themselves that discovering alien signals is not looking too propable, since they could be using so many different kinds of communications on so many different frequencies. Only hope for discovering any alien so far is if they purposely seek us out and reveal themselves.

Its hard to discover things when in essence youre both blind and deaf, at least for a time being.

That's the thing tho. I haven't accepted what's been given to me because barely anything HAS been given to me. And you dismissed point 2 as 'impossible' and point 3 as 'too vague'.

I get the fun in speculating (I've done it about other aspects of the game) but the less starting info you have, the harder any meaningful speculation becomes. We don't even know how many other species we will come across yet, so of course people are 'suggesting things without enough information' - that's what you've asked them to do!

Sorry if I sound like I'm trying to shut down the conversation, because that's not my intent. I just think you need to accept that most responses you get will be pretty general or vague is all. Maybe after the gameplay footage we'll apparently get next week there will be more to go on.

This is my opinion only, but I think it introduces a ' we are a special case' which seems very ego-centric to assume we are the ones capable of space flight and meeting the angara, when the milky way has been held back technologically for billions of years by the reapers.
But the poor andromeda natives are even worse off than us somehow. 

I'm trying to speculate... just in a different direction that you apparently want me to... and you keep attacking me in the process.  If you are indeed a scientist, then even you should recognize that you're not actually qualified, based on available data, to speculate any more accurately than anyone else about what someone else is thinking about.

BTW, your assertion that the extinct races were mentioned in ME1... they weren't.  Liara expressly said that she could find essentially no information on any of the cycles that came before the Protheans.

... and on that note, I'm joining the others who have already said that they are out of here.  Bye.

Its supposed to be a debate, thats how debates work. I haven't heard one reason from you as to why you think the writers would write less races in andromeda other than ' they would'. When I put forward my point about your correlation isn't really valid, you leave. The other guy who left was deliberetely going off topic just to be argumentative and passive aggressive. He was discussing wordplay ( my use of the word 'impossible' rather than 'close to impossible') which is hardly conducive to an amicable debate rather than the actual topic. When I called him out on it, he left. 
Science works by creating a hypothesis based on an observation without further information about how the process you are investigating works. Thats why you do experiments to verify your hypothesis. 
Yes I think it was just the protheons and rachni that were mentioned as 'extinct races' in ME1. 

Kett are definately spacefaring, they likely are also reverse engineering or using remnant technology. Leaks mention they are going after remnant vaults, so that kinda proves it.

I dont know about the angarans, could be a true first contact for them with us unless theyve ran into the kett, or are explorers themselves. I think theyre native to the Heleus cluster tough. And either they have spacefaring tech or they get some from us, since we see them on other planets, like Kadara.

Well, it wasn't a question at the time, just a hypothsis about where the writers wanted to take the story and I can tell you from the first 3 seasons in BSG, they had less information to come to that conclusion than the current information we have on ME:A. It was a massive leap.
I mean you say the first four reasons were grounded in logic. I ask you how? There were no reasons given for coming to those conclusions and I already pointed out to you if you had been reading my previous reply, that I didn't dismiss them outright. I was looking for a rationale for you think so rather than wildly throwing out random ideas. 
It is possible that the remnant were part of a greater fallen empire because the word remnant means 'part of' so probably they were part of something bigger. What caused the downfall of the remnant may explain the downfall of other races. See thats what I'm looking for, rationale in the context o the game rather than ' there are fewer races in andromeda'....what? Why? Why would the writers do that?
In your point 3 you just said the remnant were the dominant race until, something?? What does that mean?
In previous points you mention andromeda species may not have mass relay technology level for galactic travel. 
Well like why? Are is the milky way a special case given that we were held back for billions of years by the reapers?
You know what I mean?

Well a lot of people put in very good ideas and the reason why they think s, so we made some progress. The only people that didn't like the thread seem to be people who don't like their ideas challenged with new ideas. (Im not referring to you but other people) and so they get nowhere.
About the cylon thing, I guess you had to be there. It was THE major story arc plot twist of the entire series with little to no information to speculate. I figured given ( very little)available data and what was likely to be a narrative plot twist. 
Writers have had to discuss their ideas on the andromeda galaxy. So why shouldn't we do the same, even if they're wrong? In the ME universe, everything has some rationale behind it so the writers can't just throw out anything they like.
