9 Rarest & Most Valuable PS4 Games You Might Own

8. Gravity Rush Remastered

Estimated Value: £80+

When Gravity Rush Remastered was first announced, it was originally intended to be a digital-only release, however Sony later worked out a deal with Amazon to manufacture an unspecified number of hard copies exclusively for the store.

Despite being a rather niche property, the physical editions sold out pretty quickly, resulting in new copies of the remaster being resold through third parties on Amazon's website.

Back in January of 2017 the remaster was being sold second-hand for upwards of £80, and while it's dipped a little since then, the price will no doubt only increase as the original Gravity Rush continues to gain respect in the gaming world.
