Romance of the Three Kingdoms IX with Power Up Kit is a 2017 turn-based strategy game from Koei Tecmo set in classical China, now generating roughly $600/mo residual revenue with a small but engaged player base.

This title occupies a niche within Koei Tecmo's own prolific Three Kingdoms franchise, with an 84% positive rating and 57% still-playing rate despite 89 months of dormancy from developer contact. Lifetime revenue of $201k on 31k units and continued $600/mo yield suggest quiet but durable appeal to hardcore strategy fans and series enthusiasts. Best suited for a publisher seeking to revive a backlist asset with minimal dev cost, or a studio mining Koei Tecmo's catalog for localization and platform expansion opportunities. Most realistic play: revival.

  • Risk: Game is based on classical historical Three Kingdoms IP; confirm Koei Tecmo's perpetual rights to the Nine series branch and whether any regional or sequel rights are encumbered.
  • Risk: Player reports cite save-file issues affecting non-Japanese players; underlying code health and platform compatibility (especially on modern Windows, Proton) require audit before any revival campaign.
  • Risk: Three Kingdoms XI and XIII have launched since; player base may be fractured, and revival success depends on clear differentiation or enhanced localization rather than feature parity.
