At least we were revealed that it wasnt the real Aya and the little we see of Aya felt like the real deal...then she gets killed off right after.
As a big fan of Parasite Eve, I have a special kind of hatred for 3rd Birthday for obvious reasons. If I went on to explain (rather unnecessarily since so many others have done it before online) I would be here for half an hour and Im aware my posts can be annoyingly long as they are already.
But yeah, at least it wasnt the real Aya even if they marketed as such...a reboot would probably butch the real real Aya's character as a strong and yet still very human (in fact, maintaining one's humanity is a big theme in the game) female lead.
