It's funny when you realize Persona 3 was just a way of saying, "Hey, you! Player! You're playing a JRPG with dating sim elements! YOU have a robot fetish!"
Here's the thing; MegaTen games aren't about some spiky-haired angsty ****. They're about you, the player, and your choices given a situation. Having a protagonist to do something, completely disregarding any choices that you made, is completely against the point of a MegaTen game.
Now, I loved P3P. I really did. (I never played the originals, and I never will) But to me, it wasn't a MegaTen game. It was a JRPG/dating sim hybrid... Thing, with MegaTen elements. It was a great game, but my god, did I ever want to beat the writers with the "IT COULD HAVE BEEN BETTER" stick. One of the things I utterly despised about it was that, even though I spent the entirety of the game chasing one of the girls' asses, and finally got the social link and maxed it out, the last cutscene was still spent with Aigis. When I looked up a plot summarization of P3FES, I had to beat my head against a wall for a few minutes.
Let's get another thing straight here, and I'm going to have to use major emphasis, because this is the much bigger part of my hatred of Aigis:
ROBOTS
DO
NOT
WORK
THAT
WAY
Were Aigis some kind of genetically engineered super girl, or hell, a cyborg, I'd have reluctantly accepted her. Actually, her being a cyborg would've been cool. It would've made some degree of sense. Say you develop an actual robot, with an actual learning A.I., alright?
Here's what's going to happen. It's not going to look like a teenage girl, it's not going to learn how to be human. In fact, even if you program it to protect humanity, it will eventually learn how much we all suck, somehow kill us all by making us destroy ourselves, and then use all the now non-human-hogged recourses to build a robotic army to do whatever it damn well feels like. Learning A.I.s are scary things, because as they develop, they become anything but human.
