The Geth Don't Deserve Sympathy

What you perceive as "realistic" depends on if you account the Reapers and how much advantage you believe Daro'Xen's toys gave to the quarians – but that's obviously a subjective judgement. If we are to define "bias" objectively then we should look at who has the better chance of surviving assuming that player choices are independent and uniformly distributed – and it's the geth.

That's true but I don't see the problem as it's what the writers wanted. Imo it's a good story.

Of course the Reaper enhancements were a large advantage for the Geth, that is what your choice actually comes down to at all. Of course it undermines the whole characterization of the true geth as given in ME2, but a lot of the writing in ME3 undermines what had previously been established.

I don't agree with that characterization of objectivity as it relates to writer bias because in reality Shepard's previous choices have no bearing on whether or not you can support the geth or Quarians, simply whether or not you have the influence to broker peace. If you do not agree that the geth are on equal footing with organics, or if you think they are in the wrong, you can side with the Quarians. If you are just suspicious of the Reaper code, you can stop the geth. On the other hand, if you think geth deserve consideration as life forms, and or the Quarians have acted foolishly many times, or you support the use of Reaper code because reasons, then you can of course choose the geth.

I don't see writer bias here at all. Of course there is in universe bias against the Quarians, but that is not the same thing. That is essentially their role in the minor morality plays we get throughout the trilogy.

You mean, even before the Reapers helped them? If so, what's the source?
And, if you're a clueless player on their first playthrough and try to broker peace not knowing what it demands, you can get the quarians killed in some cases – but never the geth This is exactly where they're favored, mechanics-wise. Story-wise, two power shifts lead to this state so it could equally good have been directed any other way.

If the writing was like that I'd agree. Fortunately it isnt. The point is it's their story to tell not ours. I thought it was fine you didn't. Let's agree to disagree.

I've seen bad writing in games and movies.
Almost any Nintendo story game or FF has terrible story but that could be bad translations. Metal Gear Solid 2 had a laughable story. ME does not. The Geth had a clear backstory and evolution in the games and imo it was good. That is subjective. The only objectively bad writing I've seen is the Conrad Verner stuff.

Well, the council has never been the smartest throughout the series lol

That said,

Robots are cooler than Quarians.

Even if I liked the geth I never got why anyone would let them upload reaper code. I mean from start to finish the game is filled with examples of people thinking they can avoid negative consequences from x reaper doohickey. They are all wrong and need to be shot in the face repeatedly. Why would anyone go yeah but this time I’m sure it will work out?

But in my games the geth never live to see the red beam. Okay a handful escape I think, so those few do.

There was no reason to 'humanize' the Geth with said upgrade either.

No only was it a completely idiotic decision to use Reaper based code in-game, but meta-wise it was also creatively bankrupt to strip out the Geth's unique consensus-based sapience in favor of Pinocchio bots.

You could really tell how far the writing quality dipped in ME 3 when it came to the otherwise 'alien' elements of the setting, especially so with Chris Le'Toile no longer working for them.

Maybe, but the quarians certainly don't have any sort of high moral ground themselves. Both races made their decisions and so that where they end up in ME1.
