I agree with you on all you say.
Well, that's pretty boring. How are we meant to argue?
The main difference between us is that you see CIG as a completely incompetent company which is unable to learn from its mistakes. I do not.
Another difference is I suspect CIG of making a game engine instead of a making a game. But I have no proof of that too.
Not so much the whole company. Just the giant thumb at the top. Everthing devolves from him. Doesn't matter how good the rest of the company is. Its been mentioned before (based on CR's own words as well as testimonies from others) that he doesn't like people who tell him no, he gets rid of them, and his management style is "management by decree". This will always result in a company where management are all "yes men" with nobody telling the boss when he's having bad ideas. Nobody is perfect, and you always need people who will tell you that something can't or shouldn't be done. With backers absolving CR of any responsibility (not that he needs it, he has absolved himself), it does not lend itself to having confidence in CIG being able to deliver.
It will also lead to a culture of blame, since nobody wants to give the boss the bad news, so people will always find excuses or blame others for failure. It can't be the bosses failure! You can't say that! You'll get fired! But it can't be your failure either! You need to find someone or something else to blame!
As for learning from his mistakes, history suggests he can't. He's got a long history of overpromising, going over deadlines and budgets, while underdelivering. The 8 years so far on Star Citizen reinforces the view that he hasn't learnt a thing, despite him saying at different times (after Strike Commander, after Freelancer) that he had learned his lessons and would do it better next time. But here we are, massive claims of what will be, while burning through cash and time like they are without limit.
As for the making a game engine, that's pure guff. Of course they are making an engine, they need an engine capable of what they want to do to make the game. Maybe you are implying their focus is on making an engine they can licence out to others or use for other games they will create. Ok, nothing unusual there, except they might have problems with licencing the engine, since they would need the rights to do that from Crytek/Amazon.
Personally I don't think CR has given any thought as to what they would do with the engine after SC. By the time SC is finished CR will be well into retirement.
