Fun fact, the PlayStation consoles have the second largest library out of any console franchises, save for Nintendo’s. There is a massive library of games on the past PlayStations that, because of the PS4 and PS5’s lack of complete backward compatibility, have been lost to time. And it’s a shame because some of those titles are really, really good.

Luckily, it seems like Sony has taken notice of its massive back catalog. While some titles have only come back via services like PlayStation Now, others are getting full-blown remakes on the PS5, with Demon’s Souls serving as a prime example. Sony shouldn’t stop there though, there are a ton of games that deserve to be brought to next-gen, but many more that it should leave behind.

10 Want To See: Jak & Daxter

For many PlayStation 2 owners, the Jak & Daxter games hold a special place. The first entry in the franchise, Jak & Daxter: The Precursor Legacy, was a launch title for the PS2 and received critical acclaim. Admittedly, its sequels – Jak 2, Jak 3, and Jak X: Combat Racing – left something to be desired.

All the same, a remake of the original Jak & Daxter title would be a perfect fit for the PS5. It would slot right in next to the upcoming Ratchet & Clank game as a fellow golden-age platformer. The colorful world of Jak & Daxter: The Precursor Legacy would benefit from ray-tracing.

9 Leave Behind: Killzone

The Killzone series is one of those long-running revered franchises. The first entry in the series came out on the PlayStation 2 all the way back in November of 2004. Since then, it became a staple of every PlayStation console, including the PSP and PS Vita, at least until the PS4 came around.

Killzone Shadow Fall released in 2013 as a launch title for the PS4 and received mixed reviews. Some outlets praised it for its next-gen graphics (at the time) and interesting multiplayer levels. However, the game ended up being extremely repetitive, and its single-player mode was a disappointment. Since the release of Shadow Fall, the Killzone name has faded into obscurity, somewhere it should stay at this point.

8 Want To See: A God Of War Sequel

2018’s God of War was a reinvention of the long-adored franchise. It took the rage-filled god Kratos and humanized him, giving him a son and a journey that didn’t end with extremely gory patricide. The game also ended on a massive cliffhanger, with one goddess promising that they would have their revenge on the formerly vengeful god.

If it isn’t obvious, a sequel is necessary on the PS5. Besides possibly finishing up the story of Kratos and his son, the already gorgeous game would benefit from the hardware of the next-gen console. Exploring the worlds of Hel or the Land of the Giants in 4K with ray-tracing is too good of a possibility to pass up.

7 Leave Behind: PlayStation All-Stars Battle Royale

With the massive success of Nintendo’s Super Smash Bros. franchise, other companies unsurprisingly wanted in on the action. One of those companies was Sony, and it entered the fray with PlayStation All-Stars Battle Royale. This 2012 title for the PS3 pitted iconic PlayStation characters against each other in the same way Super Smash Bros. did for Nintendo characters.

Sadly, All-Stars fell extremely flat. The game released and immediately received middling reviews. In the years following its release, All-Stars has been mostly dismissed as a cheap carbon-copy of the Smash games, something that tried to hop on the train after it had already left the station. Nintendo has cemented its franchise as one of the best party fighting games, leaving no room for a Sony competitor.

6 Want To See: The Original Ratchet & Clank Games

Another staple of any PlayStation 2 owner’s library of games was a healthy chunk of Ratchet & Clank. The first three entries in the series were PlayStation classics, setting themselves apart from the crowd with wit, charm, and a whole lot of unique weaponry. The success of these games is why players are still getting new Ratchet & Clank titles.

As fun as those new titles are, they don’t capture the spirit of Ratchet & Clank: Going Commando or the insane action of Ratchet & Clank: Up Your Arsenal. If these three titles received a proper port or remaster for the PS5, they would be instant purchases for many nostalgia-seeking fans.

5 Leave Behind: Knack

Ok, all the Knack memes are good fun but this game shouldn’t be one of the next titles for the PS5’s extremely limited library. Released as a launch title for the PS4, Knack was more of a tech demo than anything else. That just makes it more perplexing that the game got a sequel in 2017.

While Kanck 2 had a much more positive reception than its predecessor, that doesn’t mean it should get a spot in the PS5’s library. The game is too dated of a platformer to compare against others like Sackboy: A Big Adventure or Ratchet & Clank: Rift Apart. Leave this license on last-gen consoles where it belongs.

4 Want To See: Ape Escape

The Ape Escape franchise is one of those cult classics that is never really forgotten. It’s always there, in the back of some fan’s mind with the hopes that one day, the goofy franchise will return. The original Ape Escape title released on the PlayStation in 1999, and the last entry in the main series, Ape Escape 3, released on the PS2 in 2005.

While the demand may not be there, the Ape Escape games are too good to be left completely behind. A return on the PS5 wouldn’t just modernize the series, it would bring fans that have given up hope back to Sony’s PlayStation and introduce new players to a wonderful group of games.

3 Leave Behind: The Order 1886

The Order 1886 is one of the PS4’s more infamous titles. It was revealed at E3 2013, and hype quickly followed. The game promised players a romp through an alternate reality version of late 1800s England as a monster hunter. When the game finally released, though, it was extremely underwhelming, offering fantastic visuals and cinematic features but lacking in actual gameplay.

While there is a small cadre of fans that wants to see The Order 1886 return in a sequel, the name has simply been tarnished. A sequel on the PS5 would undoubtedly look brilliant, but it would take a lot to regain player’s trust after the original game’s disappointing performance.

2 Want To See: Armored Core

It may come as a surprise to some, but FromSoftware did in fact make games prior to releasing Demon’s Souls in 2009. Before that masochistic game launched, starting the studio’s rise to stardom, it had another popular franchise: Armored Core. These games were a far cry from anything FromSoftware would go on to make, as they placed players in massive mechs to battle it out with other giant fighting robots.

While FromSoftware may have moved on from its franchise, that doesn’t mean Armored Core should be left on older systems. The franchise was a PlayStation exclusive during its early years, although the seventh generation titles were also released on the Xbox 360. Another company can still take up the reins and bring this classic mecha fighting game to next-gen consoles.

1 Leave Behind: Basement Crawl

Of all the titles that should stay on the PS4 for good, Basement Crawl takes the cake. This 2014 title originally had some promise: its opening cutscene depicts a grandmother convincing her granddaughter that she needs to stay in the basement for her own safety. It then goes on to show macabre torture chambers, scary clowns, and the like. But once players actually get into the game, it’s just a bad Bomberman clone.

For its boring gameplay, uninspired ideas, and poor execution, Basement Crawl has been ranked one of the lowest scoring titles on the entire PS4 library. Simply put, this game isn’t good enough to merit a port to any other platform.
