Launch condition is display, not score
Every scorecard shows launch condition (Poor / Mixed / Good) separately. A catastrophic launch followed by exemplary support can score highly — the launch record stays visible beside the score so readers weigh the full story.
Aftercare Pattern
Recovery, Stewardship, Mixed, Decline, or Abandonment — the shape of the post-launch history, assigned per game.
No double-counting
Each event is assigned to its primary category. Secondary effects are noted without additional points.
Attribute control carefully
Developer and publisher actions are separated when evidence identifies who controlled the decision. Community mods that repair developer failures are never credited as developer aftercare.
Evidence first, score second
Game → Events → Evidence → Scoring Rules → Category Scores → Overall Score. Four evidence tiers: official records (1), independent testing and archival reporting (2), corroborated player reports (3), anecdotes as research leads only (4).
Confidence is not praise
Confidence describes evidence completeness — High, Medium, or Low. A Low-confidence 90 is not the same as a High-confidence 90. No audit becomes Verified below Medium confidence, and none becomes Verified without a public correction channel, complete evidence file, and human review.
SCORE HISTORYScores change over time.
Current score, past scores, date, and reason are kept — rehabilitation and deterioration both show.
CORRECTIONSWrong gets fixed publicly.
The event record is corrected, the score recalculated, and the change logged with its reason. Retracted evidence is marked retracted, never silently deleted.
INDEPENDENCEScores cannot be bought.
No payment, favors, access, or consideration in exchange for a score. Members fund the work; they never buy scores.
SCOPEWhat the Index is not.
Not a review of whether the game is fun. Not a launch-day verdict. Not influenced by publishers or advertisers. Not a purchase recommendation.
