Market depth

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.

Three-tier spread · log scale

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.

Why this title

Why collectors care

The cultural context, the production lineage, the place this artifact holds in its console's history.

aster of Monsters is a turn-based strategy game developed by SystemSoft for the MSX and NEC PC8801. It was ported to a variety of consoles and PCs including the PC Engine CD, NEC PC9801, and Sega Genesis/Mega Drive. While it never had the same success as its SystemSoft stablemate Daisenryaku, the game garnered a loyal following. Its success in the North American market on the Sega Genesis proved sufficient for a sequel on the Sega Saturn, and an anime art-style enhanced Sony PlayStation version titled Disciples of Gaia with a Japanese role-playing game feel. Master of Monsters: Disciples of Gaia was released in 1998.
