Any kind of success at all.
Your link?
You completely fail to substantiate your claim about what Bioware wanted for the game, for it to succeed.
Quite simply. People set objectives. If they meet the objectives, it is a success. if they do not meet the objectives, it is a failure.
First of all, you still haven't even established that it's an objective in terms of success. There's a difference between wanting something from your own game, and having it be a requisite for success.
Even if Bioware needed it as a requisite, it would merely be their OWN opinion about the success of the game. Other people might have different opinions.
Secondly, people DO set objective(s) - as in a plural sense. Even if there was a way to determine, objectively, that Mass Effect 2 failed as a "Dirty Dozen" experience - which there isn't - it would still be a single objective among many others.
So, talking about a single objective that wasn't reached, in your personal opinion, as the main criteria of success is pretty ridiculous.
I reported the fact the devs intended ME2 to deliver a dirty dozen like suicide mission experience. The game does not meet the objectives. It fails.
Seemingly, others think it DOES provide such an experience. You keep pretending you can possibly convince us without even substantiating your claim that Bioware wanted this for the game in the specific way you suggest.
Even if it fails at it, it's only a single objective.
Now, you cast yourself other objectives than the devs' and assess success or failure. At this point, it is opinion because of the change of objectives.
I cast nothing at all.
But I don't claim to know for a fact what the developers wanted from the game, and I don't let my own opinion about whether the game is a success or not - rule over what others might think.
The completion of objectives is not an opinion. Just play a video game to get a taste of it.
It is indeed an opinion whether or not Mass Effect 2 provides the experience you claim it needs to succeed. Your opinion is that it fails, and others here have said that it succeeds.
Of course it is different. Stating that a pen is blue is different from stating one likes/dislike the pen because it is blue. One is a factual report, this other is a matter of taste, an opinion.
My opinion of the movie and my opinion of what characterises the movie is, indeed, exactly the same in terms of how we all differ, and how it's a subjective disposition.
You seem to think that you can, somehow, establish these things in an objective way.
Unfortunately, it's not enough to keep repeating something as a fact, if you utterly fail to prove it. You might be able to convince yourself of something like that, but I promise you that you'll fail again and again, trying to pass off your opinion as some kind of objective fact.
