Huh, I actually
really like this idea. Would it be like a open design, where you just wake up as your character one day and just walk around the neighborhood exploring and talking to people, with no clear goal at first? Cause I think a game like that would be awesome, where every inhabitant of your area has his or her own story and maybe a quest, like getting a cat out of a tree, or finding a lost bike, or helping a man file his divorce proceedings. At the end of each 2-hour run there could be a score of how much of a difference you made in people's everyday lives, for better or worse, and a short paragraph explaining what your actions that day evnetually led to (e.g. "Upon realizing that you helped a neighbor cover up robbing a drug store, your wife eventually divorced you, and your house was then sold to a young drug addict, you eventually got Ms. Norris's kid addicted to heroin, leading to his suicide 17 years after you left the community", or, if you never found a date for Ms.Norris that day, the drug addict instead is just mentioned as being a loner, whose neglect of his house lowered everyone else's property values)
Basically, what I', doing here is going through peoples posts, letting my mind wonder while trying to interpret their explanation, and typing out these thoughts. Its fun, I encourage you to try it
