Collector interest
The American NTSC version of Journey to Silius, released by Sunsoft in 1990, is easier to find complete than the PAL one, yet its reputation holds firm, carried by Naoki Kodaka's soundtrack and exemplary action design. Sealed copies reach high figures because the title ranks among the most respected Sunsoft NES games. The angle here is durable demand grounded in recognized quality rather than raw print scarcity, which was wider than in Europe.
