The Sega Dreamcast is one of the most beloved video game consoles ever. Many games released on the Dreamcast helped modern classics find their audience and become popular over the years. Unfortunately, the Sega Dreamcast was also the company's last home console with a major presence within the industry. Because of that, players are nostalgic about the console's library and hold it in high regard.

But that's not the only reason Dreamcast games are so coveted. There are a few highly sought-after gems that game collectors are constantly searching for. However, chances are they won't be getting their hands on certain rare game releases so easily. They are just that elusive and incredibly valuable. Here are some of the rarest Sega Dreamcast games you'll probably never own, unless you're willing to pay a lot of money for them.

5 Jojo's Bizarre Adventure

Bringing the Stands to consoles

If there was one word to describe the anime Jojo's Bizarre Adventure, it would probably be outlandish. The same goes for the fighting game, which was based on the anime series and manga from Capcom and released in 1998 for arcades. The game was then ported to the Sega Dreamcast and original PlayStation a year later. Jojo's Bizarre Adventure was also developed by the same team that had made Street Fighter 3, one of the most influential fighting games, with many sprites and animations being very detailed. The plot of the game was based on the third main arc of the manga, Stardust Crusaders, and featured many characters from that part of the series. The game also had series creator Hirohiko Araki as a consultant.

Copies of Jojo's Bizarre Adventure on Sega Dreamcast are hard to come by. A loose copy of the game outside its box will often be priced at around $125, without anything else. But if you manage to find a complete copy of the game, the value can jump up to $185 in total. In some online auctions, a complete-in-box copy of Jojo's Bizarre Adventure has been known to sell for as high as $300. While the game was also available on PlayStation, the Dreamcast version of the game is a lot rarer.

4 Speed Devils

Rare racing variant

The Dreamcast had its fair share of amazing racing games. One of them was a lesser-known game called Speed Devils. However, the original title for the game was Speed Demons. The game was released on Windows PC in 1998, and a year later, it was ported to the Sega Dreamcast. In 2000, an updated version of Speed Devils was released on the Dreamcast, which included online play. Speed Devils is a straightforward racing game with stages that include aliens, dinosaurs, and a number of other hazards that block the roads during races.

While the gameplay is nothing special, the packaging of Speed Devils on the Dreamcast is noteworthy for collectors. The first printing of Speed Devils featured a misprint on the box art, with manufacturers forgetting to include the devil's head on the logo. This clean version of the box art garners a higher price, valuing the game at around $200 complete in its box. A loose copy of the game with just the disc will still cost around $175 in some cases, with higher auctions reaching as high as $400.

3 Illbleed

A survival horror gem

There are plenty of great horror games, but Illbleed is an original survival horror for the Dreamcast that is also the rarest for the console. The game was released in 2001 by developer Crazy Games and was published in North America by Amusement Interface Associates that same year. The story of the game takes place in an amusement park, with six stages that have a variety of horror themes. While critics praised Illbleed for delivering an interesting experience in the survival horror genre, the release of the game was very ill-timed. Illbleed had arrived only a few months after Sega officially discontinued the Dreamcast worldwide in March 2001, making this one of the last games to release for the console.

For survival horror fans who want to add Illbleed to their collection, a loose copy of the game will cost around $170. But a complete copy of Illbleed will be more valuable. Prices for a boxed copy of the game can reach the $250 price range pretty easily. A big part of gaming history is tied to the release of Illbleed, which may justify the high price for some collectors.

2 Giga Wing 2

Last shots for Dreamcast

Some of the best scrolling shooter games can be found on the Sega Dreamcast. Giga Wing 2 was released in 2000 for arcades and was ported to the Dreamcast in 2001. Giga Wing 2 throws legions of enemies at players in a challenging, yet beautiful, display of chaotic action. The arcade version was known for displaying crazy score numbers, but the home version added some new features, such as a 4-player mode and online rankings. Critics at the time praised Giga Wing 2 for its old-school challenge and consistent levels of fun.

Game collectors love the shooters that are available on the Dreamcast, so it's no surprise that Giga Wing 2 would be so valuable to them. Loose copies of the game can cost around $130, and sometimes more. But if you want a complete-in-box copy, you had better prepare to pay more than $300. Some online auctions have been known to get as high as $400, which might be more than most fans of shmups are willing to pay.

1 Cannon Spike

Shooting things with Capcom

Originally released in arcades as Gunspike in 2000, Cannon Spike is a multi-directional shooting game that was ported to the Dreamcast that same year. The game includes a number of Capcom characters from various franchises, such as fan-favorite heroes from the Street Fighter, Mega Man, and Ghost 'n Goblins series. In addition, other Capcom characters from games like Alien vs Predator also make an appearance. Cannon Spike has players shooting at groups of enemies as they traverse a stage, culminating with a boss battle at the end.

Cannon Spike is arguably the rarest game release for the Sega Dreamcast library. And as such, the game is constantly priced very high. Any loose copy will cost an average of $200, but the value will drastically increase for a boxed version. If you want to own a complete copy, then be prepared to pay at least $300, or as high as $700 in some auctions.

Collecting the Dreamcast gems

There are many beloved games for the Sega Dreamcast, but not all of them are seen as valuable. For most Sega fans, collecting Dreamcast games is a product of their nostalgia, which comes from growing up with the console during a period when things were changing within the industry. As time goes on, many will continue to hold the Dreamcast and its library in high regard as a benchmark of gaming history. These rare game releases are true gems from a bygone era that many will only read about and look back on in the years to come.
