It's always nice when you get a remaster so good that it improves upon your memories of the original.
BluePoint Games is a studio in Austin, Texas that's gotten a bit of a reputation for being the masters of, well, remasters. Having worked on the Uncharted: Nathan Drake Collection a couple of years back, the same company is now responsible for remaking Shadow of the Colossus for the PS4 and PS4 Pro.
Shadow of the Colossus has already been remastered once for the PS3, of course. But as per Digital Foundry's comparison below (with the PS4 footage against the PS3 remake and the PS2 original), Shadow of the Colossus has been remade from the ground up.
The draw distance has been extended substantially; environments have been recreated; a new lighting engine has been added; and detail has been greatly increased, as you'd expect for a console two generations beyond what the original game was released on. Hell, just the difference in the forest scenes alone are remarkable.
If you never played Shadow of the Colossus originally, now's as good a time as any to jump on board. The fact that the game runs as a buttery smooth frame rate in performance mode and an improved control scheme is just the icing on the cake.
