'Universe-sized' video game designed by algorithms

Thirteen people in Guildford, UK are making the biggest video game ever.

No Man's Sky was first shown off this time last year, but back then it was just a mere shell of an idea, a grand promise to create a universe-sized game like no other.

This year, we're finally able to enter that universe - galaxies created by algorithms. This means players can discover literally billions of planets.

The BBC's Dave Lee meets the game's creator Sean Murray, founder of independent developer Hello Games.
