This has absolutely nothing to do with what you are discussing, but speaking of time periods... I thought it was funny in King's Quest 2 VGA (made my Anonymous Game Developers) when they had Graham go into all of the different dimensions and time periods. I don't know if the team is doing this, but maybe they can weave in the element of time travel in the games if they haven't already. I think it would make for a nice touch and it hasn't been done before except in the unofficial KQ2.
