9 Rarest & Most Valuable PS4 Games You Might Own

3. STRAFE

Estimated Value: £120+

A retro-themed first-person shooter inspired by genre icons like Doom and Quake, STRAFE was successfully Kickstarted for over $200,000. Initially a parody of video game commercials from the '90s, the action title struck a chord with gamers by indulging in the over-the-top machismo of shooters of old.

Doubling down on its throwback approach, the FPS was promoted as having the best graphics this side of 1996, marketed with the kind of tongue-in-cheek flair that publisher Devolver Digital always does so well.

Consequently, 2000 physical copies were made in anticipation of the game's PS4 debut, selling out pretty much straight away once word-of-mouth began to hype up the unique game.

Sold out now, the title can be bought for around £70 second-hand, however, if you were lucky enough to pick up a copy with a variant cover, you could be looking at an asking price of around £120.
