About Game Boy
The original Game Boy (1989) proved that handheld gaming didn't need cutting-edge graphics to succeed — its monochrome screen and legendary battery life, combined with Tetris as a pack-in, made it a cultural phenomenon. Game Boy cartridges are famously durable, so this remains one of the more accessible retro platforms to collect, though translucent color variants and complete-in-box copies with the original brick-sized manual add real value for condition-focused collectors.
Gamevaro tracks Extra Bases for Game Boy 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 Extra Bases 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 GB release dates back to 1991.
