I would love to have a very varied landscape - seas, rivers, mountains, various types of forest, deserts, ice desert, tundra, grassland, jungle, flying cities, cloud castles, crystal castles, vulcanos, large dungeons of various types, in short - all the standard landscapes and many exotic, fantastic extras.
And I would love to have an "easy" starting area, a wall that protects this area, and then harder and harder areas, until deep wasteland where nobody dares to dwell except the bravest adventurers.
No leveled scaling this time.
An extremely large main city, three still very large normal cities, and many small villages and lone houses, also pirate hideouts and smuggler hideouts.
Also various mounts and other transportation devices, such as normal steeds, but also dragons, boats, also teleporters.
