Steam-Heart's
Sega Saturn · 1998
About this game
Steam Heart's is a 2D sci-fi vertically scrolling shoot-em-up with erotic content.
The game takes place in the far future, on an alien planet dominated by seven elf-like or catgirl princesses that have fallen under the spell of a unique virus that has driven them mad and threatens to destroy the planet if all the rulers declare all-out war.

Only Blondia Varady (nicknamed "Blow") and his sister Fallandia have been spared from the disease and must pilot their fighter ships in order to penetrate deep into the domain of each princess, destroy their war machines, and administer the antidote.
Fortunately for Blow, the antidote has been synthesized into his reproductive organ, so that means there is only one way to inoculate the girls....
The player controls the fighter ship through vertically scrolling stages, trying to destroy every ship that crosses its path and reach the end boss.
The ship has a primary weapon that can be constantly upgraded by collecting power-ups, and a secondary slot for all sorts of collectible weapons that can be picked up in mid-air.
The game features 2P-cooperative gameplay and cutscenes made of still images that explain the plot and depict the protagonist's encounters with each princess.
About Sega Saturn
The Sega Saturn (1994/1995) struggled commercially against the PlayStation despite strong 2D capabilities and a library beloved by shoot-'em-up and RPG fans. Its relatively low sales translated directly into low print runs for many games, making the Saturn one of the more expensive retro platforms to collect completely — several titles now sell for hundreds of euros in good condition.
Gamevaro tracks Steam-Heart's for Sega Saturn with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Steam-Heart's to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This SAT release dates back to 1998.

Market insights
Rarity & condition

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
