I had a thought the other day while trying to draw a new overworld for my newest quest. Z1 had complete openness in its overworld, where you could go anywhere and enter any dungeon (permitting you had the whistle or the candle.) Most of the new quests i have played have puzzles on the overworld or have restrictions where you must have the sword or specific items to continue to the next dungeon. What do you prefer? openness, or restriction? LO, my first full quest, had a completely linear overworld, so that didn't matter either way.
