Thus far, the world of Destiny has a great foundation, but why not build the rest of the house? All the maps have great panoramas, but they are just low poly hills and 2D trees, not an actual open world that I can run out to and explore. Even Mars feels only about twice as big as the silent cartographer. I am slightly annoyed that in the demo the hills in the distance in Old Russia were declared "playable space" despite the fact that riding your sparrow over a small cliff leading to them results in your death. I know DLC will add more linear spaces, but the linear areas you already have are beautiful and amazing, why not set up a few interns with Grognok and have them churn out larger spaces to add to the world we can explore? I know a little bit about videogame world creation from personal experience, you already have the palettes, 3D assets, textures, and AI setups, why can't Earth have a gigantic valley filled with boulders and enemies? Would it detract that much from the game to allow the player to have at least a solid square kilometer to run around in? Going passed the same patch of dirt 15 times during a patrol is really soul crushing [spoiler]look at your activity statistics per region, I bet you'll see players prefer the Isthar Commons, not just for loot, but also because it's a fun place to fight[/spoiler]
