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 Japanese run, more discreet in the West, draws collectors aiming for the original edition in its language. Lasting demand from party-game fans sustains a steadily rising value for complete copies.
