It’s unclear exactly how this is happening, but it appears that some gamers in the US are getting full access to Yakuza 6 after downloading the demo, complete with trophies and everything else. Coming in at 35.6gb, it’s not really a surprise that the demo contained the full game.
Unfortunately, this looks to be restricted to the US version of the demo, which was only available for a short amount of time before being pulled.
This isn’t the first time it has happened, but it’s been a while. It’s definitely never a good idea to include the full game in a demo.
We apologize, but have had to remove the Yakuza 6: The Song of Life demo from the PlayStation Store. We are as upset as you are, and had hoped to have this demo available for everyone today. We discovered that some were able to use the demo to unlock the full game. 1/2
The demo is the full game, you can play up to chapter 1 with trophies and the rest is locked till you purchase it on launch, progress carries over. People found a way to play more than intended. Sega pulled the demo currently to fix the issue.
