In Legend of Zelda: Echoes of Wisdom, it's Princess Zelda herself who takes on the main character role. Her gameplay is different from Link's, but one thing that stays consistent between both characters are Rupees and their value. Rupees are the currency in Legend of Zelda games, and you'll want to make an early habit of collecting them. You'll start your Echoes of Wisdom journey broke, but there are ways to make the counter go up quickly.
