Epic Games is the maker of Unreal Engine, which is one of the biggest and most capable game engines. What is a game engine? Well, all games, no matter how diverse their play style or visual presentation, have certain functionality in common. Developers used to code all of that from scratch (and still can, if they so choose), but it makes sense to bundle all of those capabilities into one piece of software so that devs can work on the things that make their projects unique instead of continually re-inventing a thousand different kinds of wheels. This is what game engines do.
There’s a feedback loop that has now been running for decades between companies like Epic that make the engines, and developers who come up with new ways to use them. Engines become more capable as companies like Epic say “hey, a lot of devs are implementing Feature X, we should just add that to the next release.”
Meanwhile the hardware that people use to run games becomes much more powerful. Developers think up interesting ways to take advantage of all of these improvements.
Game engines are really a general infrastructure for immersive experiences—by which I mean, audiovisual productions that you can move around in and interact with. Many of the applications built on this foundation fit cleanly into established genres such as first-person shooter games, but increasingly people use these things to make art projects, movies, and commercial/industrial applications.
Nick Whiting, a former studio head and engineering director at Epic, has co-founded a company called Kumikai that, among other things, helps developers who are using Unreal Engine to create applications that are not games. Part of his inspiration came from this brain aneurysm surgery simulator. Nick generously provided me with a list of links to other non-game projects that I can’t fully do justice to here, so I’ll just drop them in:
- The “Guided Ureterovesical Anastomosis” section of this page on the Surgical Science site. Maybe a better and quicker view here though
- Tesla’s use of Unreal Engine to generate synthetic data for training AI. If you’re teaching an AI to deal with conditions that arise in three-dimensional space, you can get data much more easily and cheaply by simulating it photorealistically than by going out into the real world and shooting video.
- The inevitable NASA link. Label says it has been taken down but it seems to play.
- A mining construction simulator. “By changing things like lighting and tunnel sizes to give a bit more "breathing room"…before they blast holes in the ground, they were able to save large amounts of money and have better safety for folks that are already in incredibly hazardous environments.”
So if there’s going to be a Metaverse, game engines are going to run it. And game developers—the people who are proficient at using those engines and the toolchains that feed assets into them—are going to build it.
In 2017 Epic released Fortnite Battle Royale, which most people just refer to as Fortnite. It is an immensely successful game. In any given month, 70 - 80 million people play it. At peak it generated $5 - 6 billion a year in revenue.
This is relevant to the Metaverse because Fortnite is an online, multi-player game. 100 avatars parachute onto an island at about the same time and fight each other until only one team remains. The players can be anywhere on Earth. So in order for Epic’s engineers to make this game work, they had to solve a host of technical problems around synchronizing those 100 players’ perceptions and experiences of the same virtual space.
They’re not the first or the only engineers to have tackled such challenges. MMORPGs (Massively Multiplayer Online Role Playing Games) are a genre unto themselves and have been around since long before Fortnite. More recently Minecraft and Roblox have achieved phenomenal success enabling users to craft experiences that can be experienced by multiple players at once.
Tim Sweeney, however, has been openly stating for a long time that the goal is to develop all of this into something like the Metaverse. He’s been personally working on a new programming language called Verse that is tailored to the needs of Metaverse builders. After years of development Verse has recently broken the surface in UEFN, Unreal Editor for Fortnite, which is a system that Epic has released in order to make it possible for developers to extend the base Fortnite experience into games of their own design, and to make money doing so.
