Thank everybody for being so helpful, my game endeavor is coming alone rather well,
but i have more questions,,,

I have checked out several map editors, but I am unsure about their capability. It seems to me that they can create a room, a level, but I'm confused about how they create the out doors? I want to create a world just like World of Warcraft, do you know what program they used?
is there a free map editor that is capable of creating a world like that?
Once again, thank you for your help, i will spent the rest of my life creating this game if that's how long it will take
