I've just finished the first dungeon and town in my RPG, and I'm trying to decide whether or not I should use a world map to link the two together, or have towns and dungeons flow into each other. The only thing stopping me from having everything flow together (and it's the choice I'm leaning towards at the moment) is travelling from one side of the world to another, but even then I could execute some sort of teleportation system to do so.
I'm mainly after opinions - how do you feel about a world map in your RPGs?
