I think both should be put into the game. But how?

First playthrough you can choose the difficulty. Harder the difficulty the more difficult the enemies. They are smarter, faster, stronger, and all that fun stuff. Dungeons will be twisted around. harder the difficulty, the bigger the dungeon becomes.

Each dungeon could have several paths to the boss. On easy, the easiest path is available. On normal, its a combination of both the easy and hard. But on Hard the easy path is completely obstructed. Meaning you have to take a detour. Some rooms will be shared on all routes, but for the most part its like three different dungeons for every 1. Of course you can only play one version of the dungeon.

So this is what it would be like throughout the whole game.

Now for the second quest. Puzzles would be reworked, enemies would be at their best and in full force. In the second quest, the previously blocked routes will be open, but you will need to complete it all.

Also in this second quest, more minidungeons similar to the Ice Cavern in OoT will be open.

What does this mean exactly?

The casual players can still get a good game. If they want to try it harder they can. hardcore fans can select Hard throught he first time around, and enjoy an even harder experience the second time around.

I think this would be one bad ass game.
