I love the idea of exploration in an RPG, and I love adding it into my own RPGs, so I get what you're doing and totally approve! I've added small areas in my own games where you can go if you wish and find new items/treasure/story or character development. Things like a small beach here, or a forest clearing, or even a small shack in the middle of a dungeon.
It tends to make the world feel bigger, too.
