What the 3 questions at the beginning of kingdom hearts mean?

Answer 1

The questions asked determine the level at which Sora gains experience throught the game. Picking the first answer for all three questions will make your journey start at dawn, picking the second answer for all three questions will make your journey start at midday, and picking the last answers for all the questions will make your journey start at night. Dawn means you'll level up like greased lightning up to level 50, and then you'll have problems levelling up to level 100, aka the 'easy' playthrough. Midday means that you'll level up at a normal pace, aka the 'medium' playthrough. Night means you'll level up slowly at first until level 50, and then jump to warp speed up to level 100, aka the 'hard; playthrough.
