Knockout Kings 2003

Fight as your favorite boxers including Sugar Ray Lewis, Muhammad Ali, Lennox Lewis, Oscar De La Hoya and plenty more past winners and current champions.

There's also plenty of things to do, including a straight up arcade game (so you can beat your mates to the punch!) and a career mode, where you can take your chosen player from the rookie list to the world stage, all in one day.

Nintendo's GameCube (2001) used a compact optical disc format and was the company's first console with online capability, though it never matched the PS2's commercial success. GameCube discs are comparatively durable, making complete-in-box collecting approachable, while a handful of Japan-only and limited-release titles (some tied to promotions) are the platform's genuine chase items.

Gamevaro tracks Knockout Kings 2003 for Nintendo GameCube 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 Knockout Kings 2003 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 GCN release dates back to 2002.

Market insights

Knockout Kings 2003 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.
