With more than 155 million units sold worldwide, the PS2 remains the best-selling video game console of all time. Though its fantastic library of games certainly contributed to the PS2's success, its ability to double up as a DVD player also played a hugely important role. Not only did this eliminate the need for a designated DVD player, but it also allowed developers to cram a lot more data onto the system's optical discs.

With a 4.7GB capacity, PS2 discs were able to store almost seven times as much data as the discs used by the original PlayStation, resulting in a lot fewer multi-disc games on the PS2. To be a little more precise, only 11 PS2 games came on more than one disc, which is around the same number of multi-disc Sega Dreamcast games despite the latter's signature GD-ROMs having a significantly lower capacity than DVDs.

Compilations like Growlanser Generations and Hitman Trilogy will not be included in this list, nor will games that came with a second disk featuring audio or video content or demos for other games from the same publisher.

Armored Core: Nexus (2 Discs)

Before Demon's Souls, FromSoftware was best known for its work on the Armored Core series, with five mainline installments and a variety of spin-offs released between 1997 and 2013. Armored Core: Nexus was a sequel to Silent Line: Armored Core, which itself was a direct sequel to the series' third installment. It came on two discs, with the first, EVOLUTION, focusing on brand-new content. Conversely, the second disc, REVOLUTION, was heavily inspired by previous Armored Core games.

Cy Girls (2 Discs)

Cy Girls, or Cool Girl, as it's known in its native Japan, started life as an action figure series before later being adapted into a video game by the Japanese developer and publisher Konami. The game offers up a healthy mix of puzzles and combat and features two playable characters, with one specializing in melee attacks and the other being a master of stealth. Like many other multi-protagonist games from this era, each character gets their own disc, with Ice on the first disc and Aska on the second.

Devil May Cry 2 (2 Discs)

Most consider Devil May Cry 2 to be the weakest game that the series has to offer, with the developers' decision to include more than one playable character remaining somewhat divisive among fans. Much like many of the earlier Resident Evil games, the game's two unique storylines come on two separate discs, with Dante playable on one and Lucia's missions confined to the other. Players can also use Trish in place of either character by beating the game on Hard Mode using Dante or holding L3, R3, L1, and R2 on the main menu until a sound is heard.

Grandia III (2 Discs)

Considering how many multi-disc RPGs there were on the original PlayStation, it should come as no surprise to learn that the PS2 also had a couple of robust role-playing games in its expansive library. Grandia III is perhaps the most notable, with the game's action-packed story split up fairly evenly across two game discs. This is the same number as the first Grandia game, which was one of fifteen PS1 roleplaying games that came on more than one disc.

Metal Gear Solid 3: Subsistence (2 Discs)

Although both Zone of the Enders and Metal Gear Solid 2 were released with two discs, neither bonus disc actually featured any gameplay for their respective games, with the second disc of MGS 2 packed full of videos and trailers and disc 2 of ZotE boasting a demo for MGS 2. As a result, Metal Gear Solid 3: Subsistence was the only true multi-disc PS2 game directed by Hideo Kojima. Even then though, disc 2, Persistence, featured Metal Gear Online rather than a direct continuation of the game's story, so whether or not it really counts as a multi-disc game is somewhat debatable.

Onimusha: Dawn of Dreams (2 Discs)

RELATED: The Best Capcom Games, According To Metacritic

Before God of War and Team Ninja's fantastic Ninja Gaiden reboot series, Tenchu and Onimusha reigned supreme over the hack and slash genre. The latter was by far the most successful, with fans of the Capcom series treated to six games in as many years at the beginning of the 21st century. Onimusha: Dawn of Dreams was the last to be released in the PS2 era and features 17 scintillating stages for players to sink their teeth into. The first 11 can be found on the game's first disc, with the six remaining stages coming on disc 2.

Sakura Wars: So Long, My Love (2 Discs)

The Sakura Wars series never really took off in the west, though that didn't stop Sega from localizing the franchise's fifth mainline installment for English-speaking audiences. As a result, the North American version of Sakura Wars: So Long, My Love came with two discs; one featuring the game's Japanese dub and the other featuring the English localization. Sadly, despite positive reviews, the game failed to make much of a mark, with fans having to wait well over a decade for the next mainline Sakura Wars game.

Shadow Hearts: Covenant (2 Discs)

Koudelka was one of the most unique titles on the original PlayStation, perfectly blending together survival horror and RPG mechanics. Many consider it to be the inspiration for the three Shadow Hearts games, the second of which is Shadow Hearts: Covenant. Though it still holds onto the Lovecraftian horror elements found throughout its spiritual predecessor, Covenant leans much more into the RPG genre this time around. This includes having an incredibly long narrative, with two discs needed to cram everything in.

Star Ocean: Till the End of Time (2 Discs)

Given the series' sparse release schedule in recent years, it can be easy to forget that the Star Ocean franchise is now more than a quarter of a century old. It wasn't always this way though, with the series receiving regular releases between its debut in 1996 and the release of Star Ocean: The Last Hope in 2009. Slap bang in the middle of that period came Star Ocean: Till the End of Time, a PS2 RPG with a 45-hour main story. Naturally, this required a multi-disc solution, with the director's cut of the game split evenly across two DVD discs.

Xenosaga Episode II (2 Discs)

Given that they are widely renowned for their heavy-handed use of cut scenes, it should come as no surprise to learn that two of the three Xenosaga games came on more than one disc. Interestingly, though, it's the second and third installments of Monolith Soft's ambitious trilogy rather than the first that are multi-disc, despite Xenosaga Episode I boasting a much more lengthy main story than either of its two sequels. This was likely down to the aforementioned cutscenes, which become a lot more prominent as the story goes on.

Xenosaga Episode III (2 Discs)

Despite being widely praised by critics, Xenosaga Episode III sold somewhat poorly, with only 340,000 lifetime sales worldwide. This, together with the niche nature of the series played a big role in Monolith Soft's decision to pivot toward making Xenoblade Chronicles rather than creating six Xenosaga games as the team had originally planned. Like its predecessor, Xenosaga Episode III was released on two discs, with much of the storage capacity on them once again taken up by FMV cut scenes.
