@Dolgion Alrighty, I see where you're coming from in terms of the AI, but in the end, that seems such a damn nitpicky thing to the rest of us. With that sort of mindset with the AI going in every direction like a fireworks convention gone askew renders us unable to have a definitive and finely crafted story. It seems like a great idea, until you realize all the sort of effort they use to make that they could spend doing the other things, like making sure the combat's good, the player's stance works correctly with the environment (I will NEVER like Fallout/Oblivion/whatever's kludgey navigation) flow of story, music implementation, making sure the controls not only work but are satisfactory, etc. What you suggest takes loads of time to do with various programmers, having to individualize every single person and so on.
But doing that makes those in more recent games that shine and stand out just kinda glare with everyone else. Would HK-47 be that awesome if he had 68 freaking brothers that all act in various ways? Sure it would feel realistic, but we'd never care that much for a Meatbag hater if that happened. What about The Black Whirlwind? Garrus Vakarian? They make such excellent characters because that's what Bioware is wanting to do. They're making memorable characters, instead of spending time trying to make every single person a functional choose-dis-line-dis-happens. What you're suggesting goes more along the lines of a simulation with the vast developer tools taken away from the player just about. Granted it CAN be done... it's an idea, a massive time sink for those who have the time. But nowadays, people kinda... want to get on with it. Again, not saying the playerbase for timesinks suddenly became nonexistent, nor that there's games that no longer do that...
Hell I could argue in return that that man who gets drunk every evening suddenly wins the lottery, he could go live a new life, having his way every night. Maybe his wife doesn't leave him, maybe he tracks you down and ends you while you sleep, these are mostly very base things to result in but... again, developer time, money, sanity.
So yeah, there's games where you can possibly do everything under the sun should you feel it. But Bioware makes stories that are polished, functional, and work great in the way that they do. Do they just half-ass it and your teammates teleport around and never contribute? Okay, well, maybe only when you're not looking but still. The deepness of the universe is there if you look for it, with backstory and everything. But procedural AI in a finely crafted storyline?
To quote the Fonz, "It's like peanut butter and ketchup... both great on their own, but together..."
