This is what I had to say in short:
In terms of story, I always look at gamers who expect to read a story in an interactive medium and think "Wha!?". It's an interactive medium - YOU make the story.Taking it further, the specific ways the program recorded events would shape the story made. Like if it puts more emphasis on rescuing someone than blowing up ten guys at once...well, then the emphasis would be on rescues. You would be making the story, but the 'bard' who is recording it would also influence how it's remembered.
What I would grant is that these games, not at all right now, have any tools to record player actions and layout a story (or atleast a log of cool events). So it's easy to forget the story you just made.
But you just don't see any of this right now in games...or do you?
Remember all the stat pages of the games you've played? That record lots of stuff you've done. See, it's coming! Now gimme lots of money for just saying it first! lol!
