With some games, it pays to go through it quickly, but with most of the ones I have played, I enjoyed taking it slow. With the Myst series, it almsot requires that you move slow, otherwise you get bogged down with too much information at once or you have too little. And with every Final Fantasy, I always take them slow the first play through due to the fact that I wish to experience all the scenes or any other information that may interest me concerning the plot/characters/items/final fantasy blah.

So really, all in all, I take games slow.
