Quotes from Tim Sweeney

Unreal has to be an engine for everyone who wants to build a major game.

The thing that excites me most technologically is the ability to use VR not just for games and displaying our content, but also for creating that content. We're putting a lot of thought into what the Unreal Engine editor looks like as a VR application.

Onstage at Build, Phil Spencer said the Xbox is an open platform - which surprises me, because you have to get your game concept approved before you start developing it. Then you have to get every update approved. Microsoft has absolute control.

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 believe Microsoft has every right to operate a PC app store and to curate it how they choose.

AR is going to play such an infinite role in our lives that we have to establish clear ground rules respecting everyone's rights. That means open platform and open ecosystems and protections that put user privacy first.

There are major benefits to building a game once and improving it over a long period of time based on user feedback and behavior. It's kind of depressing to have to build a game once, take all the user feedback, and then spend the next 3 years building another game.

The mobile gaming experience is fundamentally limited by this very small screen in front of you that occupies maybe 15 degrees of your field of view. The PC and console experience, you have a 45-degree field of view. VR is 120 degrees: your entire view space. The expectations of users on the platform will rise to levels we've never seen before.

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.

I understand the concept of advertising. It makes sense. Companies want to reach customers with information about their products. It's a completely legitimate and valuable notion.

My role is more like a chairman and founder. I am used to overseeing the company's heritage and our strategy.

Ultimately, I'm an optimist.

The genre thing is overrated, and the platform decisions are overrated. It's what we see on 'Fortnite': so many of these gamers play on a variety of devices, so you can't say they're a mobile gamer or a console gamer. They're just a gamer.

We'll turn down crappy games that are submitted to the Epic Store.

At Epic, we succeed when developers succeed.

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.

Videogames have existed for almost 40 years now, yet every year, we see major and unexpected advances.

You can't build an engine that's just good for one type of game anymore. The economics don't work.

Whenever there is somebody at Epic who is capable of doing something better than me, I let them at it.

As more and more people are automated out of the economy through robotics and self-driving cars and other technologies, there will be a way to create value for other human beings online. There will be a virtual economy for exchanging value, goods and services, entertainment experiences, and all that.

All signs point to there being many virtual and augmented reality competitors, and not just a single, dominant company.

If you look at why people are paid to do things, it's because they're creating a good or delivering a service that's valuable to somebody. There's just as much potential for that in these virtual environments as there is in the real world.

Both multiplayer games and online forums have this property of virtual anonymity. Other people can't really see you; they don't really know who you are. And so the sort of social moderating mechanisms in real life, and your desire not to offend people around you, don't really adjust.

Do you remember the first three years of Steam? People absolutely hated that Valve forced you to launch their game through what some people called a virus at the time, which was the Steam client. But Steam led the digital distribution revolution: it was the first across all platforms.
