How this score was computed

The VGC Score is a weighted blend on a press-comparable 0-100 quality scale. Steam approval rates are first calibrated (95% positive on Steam ≈ 89.5 quality, since Steam approval skews high). Press and tracked creator reviews each count ~2x a player review and share one cap against player evidence (creator buy/skip calls pool into an approval rate, calibrated like Steam approval); all-time sentiment is capped and halved (it's context, not verdict); reviews of the current build carry the most weight when a fresh patch anchors the window; and a 'typical game' prior keeps small samples from pegging the scale. Because press reviews and Metacritic user aggregates describe the launch build, their weight decays as the game ages (3-year half-life after a 1-year grace). That's how a game that launched rough can outgrow its old reception once updates win players over. Reviews under 2h playtime (the refund window), non-Steam activations, and free copies are downweighted.

Acclaim gate: the raw blend lands at 88.9, but scores above 88 must be earned in front of a mass audience; this verdict rests on 999 player reviews, a largely self-selected fanbase. As more players weigh in, the ceiling rises (full scale unlocks at 100,000 reviews).

    Kugayama Shiori's Death Diary is an impressive breath of fresh air for Laplacian, bringing in the compelling supernatural style of Kazuki Fumi to create a mystery that is very well handled from start to finish. With a unique tone that manages to explore dark, harsh undertones while also treating many macabre elements in a way that doesn't feel too heavy, it's an easy recommendation in the genre.
