Direct from the Official Runescape Website:
"RuneScape is a fantasy RPG. Although it is set in a fictional world, many aspects of the game are very familiar. Like the real world, RuneScape has an economy; players can buy and sell items from shops or trade with one another individually or using the Grand Exchange and even dictate their own prices. The in-game currency is called 'coins' and allows players to purchase anything they might need to live within the gaming world. If their character loses health, they will need to eat and drink in order to replenish. If a player wants to attempt a more dangerous quest, then they will need better armour and supplies in order to succeed. They can even chop wood, smith nails and weave cloth in order to build and maintain their very own house."
