Want to see a planet-sized planet on your own desktop? You can downloadPreface: Undiscovered World on Steamand play with it for free right now.

I haven’t had the chance to play with Preface myself yet, but I’ve watched Greene demonstrate early builds of it for me twice now: once at GDC in 2023, and this yearwhen I visited PlayerUnknown Productions back in July. I was impressed both times as the engine first generated a planet viewable from outer space, then formed terrain, mountains, valleys, trees, and rocks when Greene zoomed into the surface from orbit. After those two teases, I’m excited to finally get my hands on the planet builder myself and take it for a spin.

A planet from space

Greene said the creation of Artemis “is going to be a five or 10 year journey,” and in July he told me the ultimate goal is to build “not just a game engine, [but a] world engine, or a digital place engine. But really, it’s building a holodeck, building a space that you can create whatever experiences you want.”

Preface wasn’t the only announcement Greene had at the PC Gaming Show: Most Wanted today. He also announced that Prologue, the open world survival game PlayerUnknown Productions is working on, will enter early access on Steam next year. You canread more about Prologue here.
