Collector interest
Fifth installment, refining the formula and introducing the Dream World mode and power capsules. Its collector interest joins that of the Mario Party line on GameCube, whose physical versions see their value climb markedly, with the added draw of this entry's own content that series completists want to own. The Korean run, from a tiny GameCube market, is the rarest of the entry and a major target for regional-version hunters. Lasting demand from party-game fans sustains a steadily rising value for complete copies.
