Hello Games announces No Man's Sky is coming to PC as well as PlayStation 4, saying they plan a simultaneous launch on both platforms for the ambitious procedurally generated space game. This confirms a report from last summer, but if this game isn't on your radar, here's a bit from its website:

No Man’s Sky is a game about exploration and survival in an infinite procedurally generated galaxy.

A TRULY OPEN UNIVERSE
Whether a distant mountain or a planet hanging low on the horizon, you can go there. You can fly seamlessly from the surface of a planet to another, and every star in the sky is a sun that you can visit.

Where you’ll go and how fast you’ll make your way through this universe is up to you. It’s yours for the taking.

EXPLORATION IS SEEING THINGS NO ONE HAS EVER SEEN BEFORE
Explore uncharted solar systems and catalogue unique new forms of life. Every planet’s landscape is different from the next, and populated by species never before encountered.

Find ancient artefacts that could reveal the secrets behind the universe.

Choose whether to share your discoveries with other players. They’re exploring the same vast universe in parallel; perhaps you’ll make your mark on their worlds as well as your own.
