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 90.8, but scores above 88 must be earned in front of a mass audience; this verdict rests on 4,396 player reviews, a largely self-selected fanbase. As more players weigh in, the ceiling rises (full scale unlocks at 100,000 reviews).

    Tight, inventive gameplay, cascading card synergies, and gentle, witty character-writing ensure that, while Cobalt Core might not slay Slay the Spire, it does indeed slay.

    Delightful deckbuilding that uses starship travel to build upon the Slay the Spire formula instead of merely imitating it. Outstanding.

    Cobalt Core provides a memorable story with fun characters, tense gameplay moments, and a payoff that is nearly unmatched. Despite the characters’ best attempts to escape the loop, it’s a game that you should play over and over.

    Cobalt Core was a wonderful surprise for me, and is absolutely one of my favorite games of the year. It marries two disparate genres effortlessly and has a deep but easy-to-understand combat mechanic, engaging and lovable characters, and a mysterious plot. If you love rogue-like, deckbuilder, or Shmup, you can’t go wrong with this one.

    As with any good roguelite, there are new pilots and ships to unlock, as well as card sets and modifiers to change what you’re capable of. It’s also injected with some of that Hades magic, with your pilots dropping new hints to the story with each successful run. The story and characters aren’t quite as in-depth as Hades, but it makes up for that by being funny and charming in a way few games can manage.
