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.

strododge is an unlicensed SG-1000/SC-3000 game developed and published by Revival Studios. It was released in early 2013 - two and a half decades after the last officially licensed SG-1000 game, The Black Onyx in 1987. The game is relatively simple - all the user must do is dodge asteroids while travelling upwards. The game is available in both cartridge and cassette form. The SG-1000 is one of many platforms to receive this game. The basic concept was created by Revival Studios in 2008 for CHIP-8 compatible systems of the late 1970s before being retooled for the Magnavox/Philips Odyssey² in 2011. Near identical copies to this SG-1000 version are available for the ColecoVision and MSX.
