As soon as a critical mass of people in the world gained access to devices with high-end graphics and Internet connectivity, the rise of games like 'Fortnite' became inevitable.

Fortnite, because of its visual style, it's widely acceptable to just about everyone. It's open up to a much wider audience than a realistic, military-style simulation.

I can imagine an automotive designer or an industrial designer building a product in 3D, all in real-time. That's the way a lot of people are going to work in the future.

Open platforms encourage innovation. Whenever you have a closed platform, a monopoly on commerce, and all these platform rules, it stifles innovation.

When lots of stores compete, the result is a combination of better prices for you, better deals for developers, and more investment in new content and innovation.

I would play games long enough to discover what games were doing and how they were doing it. And then I'd spend the rest of my time building.

When we're building tools, we respect developers' complete creative freedom. It can be used for the development for anything that's legal.

For the third generation Unreal Engine, we are building two versions of every model in our game. We are building a source model with several million polygons, between 2 and 6 million polygons. We use that model for all the lighting detail on the mesh. Then we go to the in-game version, which is usually about 10,000 polygons.

Streaming is something that's going to require tons of billions of dollars of investment, building server farms close to users and 5G and everything else.

If you really care about a game, spending a couple of minutes setting up payment is perfectly reasonable. It's certainly happened with 'Fortnite.'

On open platforms like PC, Mac, and Android, Epic's goal is to bring its games directly to customers.

Epic started out with scripting languages in the first generation of the Unreal engine in 1998. I wrote that. There's a place in my heart that comes along with the simplicity of programming in a scripting language.
