Milestones in the Developer Overview

Stage Documented target
Proof of Concept Join, win/lose, build, assign units, fight, basic classes/counters, resources and budget, save/load

Alpha Feature complete, at least five handcrafted maps, Occitan and German variants
Beta More maps, map generator, scenario editor, Ranked, mods
Gold Testing, feedback, polish, tutorial and main campaign

Source: Developer Overview slides 15–19. These are planning targets rather than release commitments or proof that every feature is complete.

Differences to preserve

  • The old pitch says “Early Medieval”; the current project/GDD context is the High Middle Ages around 1200.
  • The older GDD sometimes used different Alpha/Beta definitions. Developer Overview and Trello use Alpha as Feature Complete and Beta as Content Complete.
  • The deck groups DLCs as New Lands, East, South and Raiders. Trello numbers Western Regions, Byzantines, Seljuks, Mongols and Almohads differently. The deck also mentions Mamluks.
  • DLC_Factions gives Arabic for Almohads; the Developer Overview gives Amazigh.
  • Some apparent numeric fields are read as dates, including DMGSys!N4, DMGSys!Q3 and GameSystems!I22. Earlier Excel auto-conversion is possible; do not guess the intended numbers.
  • Language review and implementation are at different stages. The annual review does not establish that every associated feature is finished.
