Trouble is that you've moved away from the character creation & background chapters (ch 1&4*) relevant to the process of creating a character & hit upon page 6 in the introduction instead of the individual sections that are about actually going to be in contention.If player behaviour is so easily affected by minute wording choices, then certainly it also affected by clear directive like this:
"Your DM might set the campaign on one of these
worlds or on one that he or she created. Because there
is so much diversity among the worlds of D&D, you
should check with your DM about any house rules that
will affect your play of the game. Ultimately, the Dungeon
Master is the authority on the campaign and its
setting, even if the setting is a published world."
* Maybe 2 as well depending on howyou define character creation.
