Sony is celebrating 5 years of the PS4 by allowing players to create a personalised video showing their trophy stats on the console. Head over to the PlayStation website to get your own video created.
The video is created automatically from your PSN ID and trophy data, and shows various PS4 stats, including total hours played, total trophies earned on PS4 games, and your rarest trophy.
You can check out my version of the video below:
A clever person who goes by handle Gamstat has managed to convert the trophy stats into a estimate on how many copies a particular game has sold.
The approximate sales was calculated using the number of players who own the rare trophy (as shown in the videos), multiplied it by the rarity of the trophy (which is shown on the PSN), to work out how many people have played the game in question.
