Collector interest
The Game Boy port of Rampart, published by Jaleco in the US, keeps Atari's original arcade idea: castle defense alternating shooting and rebuilding. It is one of the few viable real-time strategy games on the monochrome handheld, giving it a recognized niche among genre fans. The NTSC edition stays accessible, but its play-design singularity, more than its scarcity, sustains steady and lasting demand.
