“ can spend all this time tinkering with making the perfect procedural generation algorithm and it turns out it makes things a little bit awkward because they’re not necessarily considering the sorts of design choices a designer would make –– and players can tell,” Martens says. But Martens says there are definitely tradeoffs that “Starfield” may have to contend with. PCG can seem like a massive boon for game designers, especially those on smaller teams that don’t have the resources a major studio like Bethesda has. “It’s like a multi-tiered generation system.” “If has crazy weather, you can add a bunch of water and you can slowly add all these things on, which is usually how you have to do it where you start with something very simple and then you add things on to make it more and more complex,” says Colan Biemer, a doctoral student at Northeastern whose research focuses on AI and PCG. Why the video game industry is making a big mistake by ignoring older adults “ say, ‘Let’s first make a bunch of hills and valleys, and we’ll make that appear more natural by then simulating the process of erosion that would add variation and smooth things out.’”Īfter creating an array of spheres and the planetary paint jobs, Bethesda could then add further layers of procedural generation to create countless combinations of weather, gravity and lifeforms for each planet. “A lot of terrain generation algorithms work by simulating erosion,” Martens says. Some noise algorithms even borrow ideas from how natural processes work to craft virtual spaces. Martens says Bethesda could have used something called a noise algorithm, “a fancy way of making things look really random in a controlled way,” to generate the foundations of its planetary surfaces. Howard has stressed that “Starfield” also has more handcrafted content than any other game the studio has put out so far, including massive cities and more than 200,000 lines of dialogue.

Discussing the team’s use of PCG in an extended gameplay overview, Jean-Francois Levesque, lead technical producer on “Starfield,” said it involves a foundation of PCG complimented by handcrafted elements like flora fauna, space pirate camps or caves. With “Starfield,” Bethesda took that approach a few steps further, going from single levels to entire planets. “How big do I want my level? Where do I want my corridors to be? How connected do I want it to be? … Once you enumerate those, it’s easy to sprinkle a little randomness into each choice point and come up with a bunch of different variations.” “A lot of times, the way these things work is you can describe the design process as a sequence of choices that you would have to make,” Martens says. A PCG tool could pull from a set of elements –– like level size and enemy placement –– and randomly create levels with different combinations of those elements. Martens says players often experience PCG in roguelike games where players run through and die in levels over and over again, and each “run” involves a different set of dynamically generated levels. Howard has openly talked about using PCG not just in “Starfield” but in the studio’s other games like “The Elder Scrolls” and “Fallout.” It includes a broad range of tools that are commonly used in game development.

It’s why the next thought many people had was, “How?”īethesda has offered few details about how it designed an entire galaxy, but Howard has confirmed that a method called procedural content generation helped achieve the scope of “Starfield.” Chris Martens, associate professor of game design at Northeastern University. It’s not just an open world it’s an open universe. 6, allows players to fly, shoot, talk and explore their way through an entire galaxy. Set in the far future when humanity has cemented its place among the stars, “Starfield,” which hits Xbox Series X/S and PC on Sept. To say the scale of “Starfield” is ambitious would be an understatement. When Todd Howard, director and executive producer of Bethesda Game Studios, announced in June that the team’s upcoming, highly anticipated game, “Starfield,” would feature a galaxy of more than 1,000 planets, fans were beyond excited.
