Here's 88 minutes of Firaxis playing Civilization 6
The Civilization YouTube account has put up a video of two of the game's designers playing through Civilization 6.
Civilization 6 is due to release on October 21 for PC.
Designers Ed Beach and Anton Strenger sit down with the game, playing as Brazil (in celebration of the Olympics) and walk through nearly 90 minutes of world conquering.
That's a whole lot of Civilization - by far the longest chunk of continuous gameplay footage we've seen. The two commentate the action and provide insight into the game's design.
