Analyst notes (AI-assisted)

Note written 2026-08-22; the live figures above take precedence over any numbers in it.

A 2012 point-and-click detective adventure from Frogwares starring Sherlock Holmes investigating a poisoning mystery that spirals into a larger conspiracy.

Testament generates $2.2k/mo residual revenue on a $1M+ lifetime base despite aging mechanics and a dormant dev presence (no posts in 38 months). The 80% positive rating and 241k lifetime units suggest strong franchise loyalty within the Sherlock Holmes enthusiast segment, but the game's mechanical friction (pixel hunting, puzzle pacing, controls) limits mainstream appeal. For a publisher holding Frogwares IP, this is a low-effort catalog cash cow; for third parties, acquisition alone is unlikely valuable given the licensed Sherlock Holmes property. Most realistic play: watch.

  • Risk: Sherlock Holmes IP rights (trademark, adaptation) typically vest with the Conan Doyle Estate; Frogwares' license to develop games may not be transferable or may have expired.
  • Risk: Reviewers consistently flag aging visuals, dated controls, and pixel-hunting design; porting or modernization would require significant engineering investment.
  • Risk: Peak players of 19 in the last 30 days and 9 concurrent now indicate the active audience is boutique; mainstream revival would compete against recent, better-funded detective titles.
