There'd better be mechs in the next game

The uprising is fine, and if you read the book, reasonably well written (does a very good job of getting into the head-space of Sloane Kelly and Tann and some others, and the uprising makes perfect sense). 

The problem is relying on an external source for a significant part of your backstory. As the game expects a lot of players to have read the book, it doesn't provide a satisfactory explanation in-game. 

Could be worse, we could be like destiny.......

Like Masked Empire for DAI, somewhat.

OK, spoilery summary of the book

They won't go back to cryo because there's no guarantee they'd ever awake again. They had already faced that once with the 600 year journey, and were not willing to face it again on the say so of a low-level technocrat no one could ever learn to trust. They're also dealing with internalised grief because (non-asari) everyone they ever knew has been dead for 6 centuries. There's a difference between knowing that intellectually and coping with it when they wake up. And just having gone through a prolonged period of grief because it got bound up in workplace issues, I know for a fact people don't make the best, most rational decisions in that situation.

Why would people follow the directions and orders of leaders who they did not choose or expect, and have also do not trust or respect. That's the crux. Lots of very intelligent and motivated and slightly crazy (all prerequisites for the Ai) people, many dealing with crippling grief, and many also with mild brain damage from cryo (see Paradise on Elaaden), losing faith and trust in their obviously incompetent leadership. I will point out that Calix (Corvannus is his first name, or is it last name?) was probably the most respected character in the novel, and it all hinges on his need to protect his crew. He also knows how bad the situation is, and feels striking out has at least as much chance of success as following Tann's direction.

What the book does particularly well is showing how everyone's actions (apart from Spender) are reasonable, given their PoV and personal prejudices and situation, and the information they have at hand.

Remember that movie "2012"? The general premise is: when things go south, people become even more selfish. And that guy wrote a book where he is stating "when things go south, people stick together". I think you would be surprises how true this actualy is.

I think some random guy most certainly think this way, better be alive for 6 months and then die a horrible death.

But the people aboard the Nexus are not some random guys.

Wwill try to explain it with some imaginary numbers.
There are 1000 people awake on the Nexus, everything is crippled/defunct and supplies last for only 1000 days. So, unless they fix the tech, everyone is going to die in 1000 days (most likely a horrible dead, as starvation is pretty bad). Obviously, they are incapable of fixing the tech.
Now they are confronted with the option: you go back to cryo, so we can wake up 1000 technicians who can fix the problems in 1000 days. Then we can wake you up again.
Even when the chance to fix the tech is very small, you are going to do it, because the alternative is "death in 1000 days" (btw knowing when you die is not realy funny). Also, there is this slim chance an Ark shows up, finds the Nexus, fix the problems and they wake up again as well.

You say, they already woke up after 600 years, they are not going to cryo again. Why not? They certainly knew what they are doing and got closure before going into cryo. As I said earlier, there are going to be psych evaluations over and over and over again so you get people who are not "emotionaly" distracted this way, becausae if you have people like this, you bring a very unstable element into a very delicate situation, you wont do that and most certainly, the AI leadeship back in the milky way didn't want it either.

Next you say, they do not trust a low level technocrat. That is actualy a good point. But then again, there are just two options: go to cryo, wakeup tech personel and eventualy stuff gets fixed, or die. Maybe they rely on themselves to fix stuff... but why are most of them sitting idle in their quarters? Maybe they do not trust the techs that replace them? well, do you remember? They are handpicked, so pretty much experts and profesionals. I know what I can do, if I can not do it, I call someone who can and not going to try to fix it myself... alas, I am an expert and profesional too... not like my brother in law, who thinks he is capable of everything and knows everything, but he can not and do not and makes an idiot out of himself all the time, unless he meets someone who knows even less. But people like that are not going to be aboard the Nexus, and if they are, in this case I say "hell yeah, this uprising is possible" then it is an unbelievable fail at the end of the guys who recruited the people and put them on the Nexus...

Back to a previous topic, you speak about "internalised grief" while on some level true, I know a lot of people who would not deal with it, they just would not care (one of the reasons why I do not have a problem with the Ryders showing low emotions becaus dad is dead). And there is this other stuff: all the psych tests and briefings are there to prepare you for exactly this, when you wake up, everyone you knew is long gone.

The problem is, it would all make (more) sense if there would be, mostly, random guys aboard the Nexus. But there are not. When you have 100.000 people for the AI, you are going to put your best aboard the Nexus, as the Nexus is the spearhead and most likely under the highest pressure to make things work. Like my brother-in-law, he is a mechanic, but NOONE who is sane would put him aboard an oil-rig, doing so is playing with fire (and lives). If BW want to tell us "but there are such people aboard the Nexus"... then THAT is unbelievable. Such people may be among the regular colonists on the Arks, but certainly not essential personel.

Btw people follow leaders, inadept, incompetent leaders, they did not elect all the time. Why would this be any different? There is that one question: what the hell are they trying to accomplish? Do they think anarchy is a solution to the problem? Do they realy thing "disobbeying" (even a stupid leader) is going to fix anything? What if they won? They would replace the hated Tann (or someone else, it does not matter) and then what? They would actualy have to do the very same shit Tann wanted to do and they opposed. Yah great. Idiots do that, actualy that is an insult to common idiots... people without brain act that way. Not even my brother-in-law is that stupid.

I gues we should call it off. I am never going to believe it. And I gues I am never going to convice you . So lets agree to disagree and be on our way.
