World Heroes 2 on Super Famicom carries the original Japanese title and the SFC cardboard box with spine card, the format prized by fans of SNK/ADK versus fighting on the console. The Japanese release stays the most affordable route to this brawler, yet a complete copy with an unbent spine and clean manual quickly separates common lots from tidy shelf pieces. Niche appeal, driven by fidelity to the neo-arcade port rather than any genuine scarcity.
