The original story is below.

The PlayStation 4 port of acclaimed PlayStation 3 adventure game Journey is available now on PlayStation Network. The new version is pretty similar to the last-gen edition, but runs at an improved 1080p/60fps.

The re-release supports Cross Buy, which means people who purchased it already for PS3 will be able to download the PS4 version for free

When it originally launched on the PS3 in 2012, Journey was met with critical and commercial acclaim. It was the fastest-selling PlayStation Network game ever at the time, and it currently sits at a 92 on Metacritic.

GameSpot's Journey review scored it a 9/10. Critic Jane Douglas wrote, "Its deliberate ambiguity brings on the urge to speculate on deeper meanings, but meaning here is bound to be personal, and best discovered for yourself. Discover it you should."
