This doesn't really describe the game itself, more rather the technology. I get the distinct feeling of early 2000's game marketing speak when all the talk was about "emotion in games" and how powerful processors would allow for more advanced AI, how just more horsepower wasn't the only thing that mattered. It was of course, just a selling tactic, because Sony knew that there were a group of users who weren't sold on the PS2's specs alone. As we know, for all the promise, we are left with a mainstream gaming landscape thoroughly devoid of emotion.

Would this game also have some elements of Shenmue? Shenmue was a good game, it did focus on intangeable emotional aspcets rather than hard-coded interactions. Searching the house and finding various pointless--but sentimental--items.

Your pitch tells me nothing of the story, or what shape it takes other than "it's innovative!", which I heard regularly in that transition period between the 90's and the early 2000's.

The idea of your player moving about after you've quit could fall into the category of "that's technical cool, but not fun to play". If you return to your character, after having murded a tramp, and your player is in a supermarket buying milk, you're going to have difficulty remembering where you are, what you were doing, what you are supposed to be doing (in the story) and likewise. It seems like a disconnect to have a role playing game, where by 'someone else' is playing your charcter when you're not there. Yes, you can switch the feature off, but if there has to be an option, that means that the idea is not sound enough (or supported by other features enough) to begin with. You would need some kind of feature that let the player track what it is they should be doing, and discovering where their player has been whilst you've been away. (kind of like the "flashbacks" when you load your game in later Pokemon titles).

So, I'm sure you have somthing more clear in mind that you're sure of, but your pitch is not really identifying why it is I would want to play this game, asides the whizz-bang technology. I come from a bit of different gaming background than Clint, so I don't think I can draw as many parallels as he can here.
