Open-world video games have become hugely popular in recent years, but there is a lot that goes into them. A big part of it is just making an engaging world. After all, if there is nothing interesting about the world, players will not have much incentive to explore it. Building an exciting open world requires a lot of detail. A lot of work has to go into designing terrain, natural features, different types of environments, characters who may be encountered in specific areas, and of course buildings. Unless the game is about surviving in an extremely remote location, there is likely to be a human presence in the world and, with it, buildings. Many great open worlds will include buildings of all shapes and sizes. They may be houses, castles, lighthouses, skyscrapers, towers, temples, shops, restaurants, and lots of other things. They may be brand new or very old. But buildings of some sort can usually be found.
