Back in 2006/2007, DBN and I were going to create a game called Shadowcast, an MMORPG.
This would have been the map:

What I love about this map is that it is geographically feasible, unlike Runescape where deserts are a short walk away from icy mountains, and tropical islands that are square in shape.
Geilenor is seriously flawed... seriously.
Mine is all plains and forests, with two great mountains in the middle.
It's only an island, but to give you a sense of scale, the town in the bottom left, Clara, is about the size of Varrock.
So there is a lot of wilderness and no mans land in between, but truly that is where all the excitement is.
I would have placed great roaming boeasts, haunted sections of a forest, travelling minstrels that you could only stumble on by chance etc.
It's a game where the cities are only starting points, and the real adventures are out in the open wilderness.
And please do look at the map and imagine the backstories to it.
I spent at least 30-40 hours inventing this world.
I made sure all the names were significant.
There is not a single insignificant name.
I'll name a few now:
Dendon's Teeth (top of the map) - A series of rocky outcrops in the water. Dendon is an underwater beast that will die if it is ever seen by a human. It is extremely powerful save for this one weakness. It doesn't actually appear in the game, but it causes great ocean storms and whirlpools... so no it is never seen.
Fratres (centre-left, by the lake) - The latin word for "eternal bond of brothers". A community of spiritual men who worship the land's deity, also skilled in a westernised version of ninjitsu. They develop cutting edge methods of assassination (via weapon technique, poison, the lot) but they kill for the greater good.
The Pilgrim's Sea (bottom left) - This land (since it is an island) was undiscovered by man for a very, very long time. The first men who arrived 800 years ago were pilgrims escaping persecution in a distant land. They founded the city of...
Geroba, which in their old tongue translates to the meeting point between the earthly realm and the spirit world, though this is all but forgotten by modern man. The city fell into ruin under mysterious circumstances and was abandoned 500 years ago, and then in the last century reclaimed and rebuilt. The city now looks like a hybrid of the old style and the new style of architecture.
Clara (near Geroba) - The town near Geroba, named after the wife of a ruling elder in Geroba, who reclaimed the city in the last century. It is a new town, built around a giant statue of Clara, who gave her life in exchange for her husbands, who was mortally wounded in a hunt. She was one of the few people who knew the
incantation of life, which allows the life force of one person to be moved into another. This incantation of course can be used for great evil, but so good was she that rather than sacrifice any other living thing, she gave herself up to save her husband. When her husband had recovered, he left Geroba and spent all his wealth building Clara in her memory.
Unnammed Village (near Clara) - This is the starting village for all player characters. You wake up on the shore with nothing but a harp-like instrument (but not quite a harp) and a small boat, not remembering anything of your past. The village has the basics of life in Ferona. A chapel for the worship of the diety, docks for fishing, a town hall etc... the whole village is built around the grand oak, next to which is a deep well that draws water from near the oak's deepest roots. It is said to give long life to those who drink from it. This village is made of people who left Clara, seeking a simpler life without the complexities of living in a big town.
______________
Those are six names on the map.
Imagine what I thought up for the rest!
I still want to turn this into a game.
PLEASE comment with your thoughts. Don't just read and close, or tl;dr
