Legend of the Red Dragon II: New World
A massive world map permits movement between numerous cities and regions and involvement in their respective political intrigues (and outright military campaigns!) against each other; alternately, a player wishing to fish on the end of the dock or collect berries for Mom to bake into pie can happily play on that scale as long as they like. There's no shortage of quests (especially with the option to include user-contributed in-game modules) and no lack of opportunities to increase experience through the slaying of random encounters. On the other hand if you prefer you can just sit around the tavern or picnic blanket and chew the fat with your buddies, exchanging comments and trading curious items acquired in your journeys.
