Note written 2026-08-24; the live figures above take precedence over any numbers in it.

A 2016 grand-strategy sim from Koei Tecmo where players guide Japanese feudal states through 16th-century political and military unification.

Nobunaga's Ambition: Sphere of Influence - Ascension generates $716/mo residual revenue from a stable 71% positive rating and 23.65-hour median playtime, suggesting strong product-market fit within a niche. The title sits quiet but viable: 170 concurrent players, zero posts from the developer in 4 years, and a recent discount (0.31 months ago) signal neither active support nor abandonment. Ideal for a publisher seeking low-risk IP licensing play or a portfolio buyer looking for a dormant turn-based strategy catalog asset with minimal maintenance overhead. Most realistic play: licensing.

• Risk: Nobunaga's Ambition is Koei Tecmo's proprietary historical-strategy franchise; any transfer or revival requires explicit rights negotiation with Koei Tecmo proper, not the developer alone.
• Risk: 119 months since last build and zero developer posts in 4 years indicate the codebase is unmaintained; OS deprecation, engine fragility, and Steam API drift could emerge without active triage.
• Risk: Elasticity of 1.88 signals price-sensitive demand; the current $59.99 list price may suppress discovery compared to established Paradox grand-strategy titles at lower entry points.
