"We want trading to be fun. We want it to be understandable, because already the game’s already quite large," says Sean Murray, co-founder of Hello Games and the one of the lead architects behind No Man's Sky

In the video above, which contains lots of new footage, Murray explains in greater detail how the economy of No Man's Sky works. Players can acquire resources from the planets they visit, and sell them at planet-based trading posts or space stations in orbit. Elements found on the surface of a planet can be 'crafted' to create more valuable 'products' which can be sold. Another way of making a profit would be to take a particular element to another part of the universe where it is less common and, therefore, more desirable to traders in the region. Players can share information about the planets they've visited, including which elements are particularly abundant.Or if you don't want to trade at all, you can approach No Man's Sky purely as a space game, journeying between orbiting stations, dealing in resources collected by other players.If you want to know more about what it's like exploring No Man's Sky, read our in-depth exploration of its beautiful yet lonely universe, or watch 18 minutes of new gameplay in the video below:For everything on No Man's Sky this month, be sure to check out and bookmark our IGN First hub.
