Sega Cancels Yakuza 6 Song of Life Free Demo After Gamers Unlocked Full Game (businessinsider.com)
Sega pulled the highly anticipated "Yakuza 6: The Song of Life" demo this week from the PlayStation Store after discovering some players had inadvertently gained access to the full game using the demo. From a report: This discovery came only hours after the demo was initially released for PlayStation 4. The Japanese video game company tweeted, "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." [...] When the demo was initially released it required more than 36 GB of storage, to the surprise of many video game critics. Kotaku, an online entertainment publication, suggests that the demo was so large because it actually contained the entire game, but was supposed to restrict everything beyond the first few stages of the game.
(Though I've read somewhere that Id *DID* make the same blunder with the shareware CD of Quake1. There was only a simple registration procedure that was supposed to unlock the full commercial game with extra episodes out of the shareware CD, the same way here the full Yakuza6 can apparently be unlocked out of free 36GB demo).
You read correct. The Quake I shareware CD not only contained the full version of Quake, but also full versions of the entire id FPS library at the time (Doom, Doom II, Heretic, and I think even Hexen), all made available for free by using a little utility called 'qcrack'. Man, discovering that was like discovering plutonium for 14 year old me.
