No; you are special because you are ultimately one of the lone survivors after the containment breach. 990 can predict this ahead of time, he can predict everything that happens in the future. And 990 can appear to anyone in the Foundation.
Being a survivor doesn't make your character special, unless he is the Chosen One or something like that. The protagonist, at least at this stage of development, is nothing more than a random Class D who is just lucky enough to be controlled by you, the player, and thus not die. That's it. Like the random soldiers you play as in Call of Duty or Medal of Honor, etc. D-9351 or whatever is not the Miracle Child spoken of in the Great Holy Prophecy, here to bring balance to the Force and drown in flame the mountains of man, so on and so forth. Unless we actually do something that has earth-shattering consequences to society/humanity/reality, our character is no one special. Just a guy trying to escape a prison. He ain't the first.
And I agree with you that SCP-990 can predict this ahead of time. He can predict anything ahead of time. I'm sure he knows the exact time and date of the next shit I take. But that's not important enough for him to appear in my dreams and talk to me about it. Why is our character so important that 990 must appear? If the answer doesn't extend beyond "990 is cool" and "our character is the protagonist", then perhaps 990 shouldn't be there.
See, don't misunderstand, I'm OK with having random SCP's there, but for the purposes of atmosphere building. SCP-012 serves no purpose other than to build atmosphere, to show the facility as a stark raving madhouse that is now unchecked (I would have a person pushing around SCP-382, just for the sake of weirding the player out). But to take SCP-990 and put a scene in there that implies some greater importance and not follow up on it is just silly. It just drags out the intro for absolutely no purpose, and takes Regalis's focus away from parts of the game that need more immediate attention. For comparison's sake, imagine that after watching SCP-173 escape his chamber in the issue, we never see or hear from him again. All that buildup for a non-character. That would be pretty bad, right? It's the same thing here.
