Seaman

Ever want to raise your own pet, starting with nothing but a tiny egg? How about raise him to be a smart-mouthed, viper-tongued companion who listens to you and gives you a dose of smart-ass advice? Look no further than the lab of Dr.

Jean Paul Gassé, who left you a few eggs from the mysterious creature known as the Seaman.

Sega's final console, the Dreamcast (1998/1999), was ahead of its time with built-in internet connectivity and an influential library, but a short commercial lifespan cut its game catalog short. That abrupt end means Dreamcast print runs were smaller across the board than a longer-lived console would have had, and it's now one of the more actively collected fifth/sixth-generation systems specifically because of that scarcity.

Gamevaro tracks Seaman for Sega Dreamcast 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 Seaman 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 DC release dates back to 1999.

Market insights

Seaman has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.

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.
