elcome to GameCube World!! (also known by the informal name Peach's Castle) is a tech demo for Nintendo GameCube. In 2001, Nintendo sent various developers an interactive Tech Demo in order to show them the graphical capabilities of their new console as part of the Nintendo GameCube Software Development Kit. In this demo, the player controls a red arrow that can go through various places in Peach's Castle from Super Mario 64. In different rooms it shows different graphical effects, which includes the following: large textures, bumps and shadows, anti-aliasing, local lighting, projection textures, environment mapping, and maximum polygons. The castle is referred to in the game as Peach Castel (castel is an old French word for castle).

What it's actually worth
The three-tier spread, verified comparable sales, and where this title sits inside its cohort. Live snapshot lives above in Pulse; this is the time-and-context layer.
The same game at three prices — Loose, CIB, and Sealed on one ruler. The scale is logarithmic: each gridline step is 10×, so the distance between bars shows the size of the jump between tiers.
