What is the "WC Canon"? Is it written down somewhere?
I’m sure you know that the canon is based, first and foremost, on Origin’s conceptions of the WC universe.
Is the only rule that the story cannot conflict with the WC timeline as it exists (can we write a WC story with Klingons and Vulcans?).
Conflict is fine (and fun!) as long as there’s the possibility of resolution.
My sense of your objection to P2 is that Origin has crafted a “bad” WC story because the idea of the Tri-System is just not appealing to you. To be sure, that’s absolutely your call. But you shouldn’t argue that your personal disappointment is somehow proof positive that the Tri-System is not and could never be a part of the WC universe.
Or is there a rule that states that any WCU story must contain no less than X number of vague references to star systems or organizations?
Mysteries or “gaps” in the storyline give us something to puzzle over and reason out on our own. We don’t need or necessarily want Origin to spoon-feed us every little fact or confirm/discount every possible plot twist.
Look, EA/Origin can make any kind of game and call it "part of the WCU"; it doesn't make it one.
On the contrary, it does. Origin as the creator has the absolute right to say what is true and what is false about the WC universe. We as the “audience” have the absolute right to applaud, boo, or even walk out, but
not rewrite.
But hey, if you & Origin want to call it WCU then fine - but I wasn't sold.
No, in terms of canon, Origin has no obligation to convince you that the Tri-System is a part of the WC universe, rather
you have the burden of proving that the Tri-System
isn’t, and you haven’t done that.
