When Sony re-released PS2 games on the PS4, many people were surprised by their high price. Sony has defended the price point highlighting the fact that more happens behind the scenes than meets the eye.
The reason these old PS2 games cost a lot is because they are more than just ports. Yoshida says the games have trophies so it takes time to add them in. He goes on to say that there’s also “QA and licensing and everything to bring back these games” too. This is why he feels the price they have set is fair. All these factors take time and money for them to bring PS2 games on the PS4.
The licensing part might be the biggest barriers to overcome. Microsoft has to deal with this type of thing when trying to bring Xbox 360 games to Xbox One. It was noted by some users that some songs from the GTA games were missing in the re-releases due to expiring music licenses.
Sony is planning to release even more PS2 games on the PS4 in the near future on a regular basis.
