Thanks for the welcomes. :-)
The idea of going back through a game for the story is interesting -- I would have thought that doing so would be boring, because you'd know all the ins-and-outs and secrets, and all the mysteries would already be solved. But then I thought about it a bit more... and considered how often I re-read the same books over and over and over again, and never get tired of them. Of course a game's not going to be any different in that respect.
Although some of you have mentioned replaying more when you were younger, I don't think I would have had the patience to replay a story/text-heavy game when I was young (if I even had the patience to play it in the first place, that is)... Well, I would have by high school, but that was during my off years. I think I'd be much more likely to replay now than then. I've also found myself sometimes replaying much more slowly -- i.e., when I have just a short while to play, I don't want to let myself get too sucked in to something I won't have time to spend hours on, so I'll just have a few minutes at an old game, where I know how it turns out, and I won't forget what I've been told to do next. (I do that... irritating, that is. And rather sad. ;-))
