💻 패턴

Gacha pity system (확률 보장)

// Genshin-style soft pity at 74, hard pity at 90
public class GachaPity {
    private int pulls = 0;
    private const int SOFT_PITY = 74;
    private const int HARD_PITY = 90;

    public bool Roll5Star(System.Random rng) {
        pulls++;
        float baseRate = 0.006f;
        float rate = pulls < SOFT_PITY ? baseRate
                   : pulls >= HARD_PITY ? 1.0f
                   : baseRate + (pulls - SOFT_PITY + 1) * 0.06f;
        if (rng.NextDouble() < rate) { pulls = 0; return true; }
        return false;
    }
}

Elemental reaction (Genshin)

public enum Element { Pyro, Hydro, Cryo, Electro, Anemo, Geo, Dendro }

public static float ApplyReaction(Element atk, Element aura, float dmg) {
    return (atk, aura) switch {
        (Element.Pyro, Element.Hydro) => dmg * 1.5f,    // Vaporize
        (Element.Hydro, Element.Pyro) => dmg * 2.0f,    // Reverse Vaporize
        (Element.Pyro, Element.Cryo)  => dmg * 2.0f,    // Melt
        (Element.Electro, Element.Hydro) => dmg * 1.0f, // Electro-Charged
        (Element.Dendro, Element.Hydro) => dmg * 2.0f,  // Bloom
        _ => dmg
    };
}

Live-service version cadence

# Genshin / Star Rail 6-week patch cycle
patch_cycle: 42_days

🔗 Graph

• 변형: HoYoverse
• 응용: 원신(Genshin_Impact)
• Adjacent: Monetization (BM)

🤖 LLM 활용

언제: anime gacha design reference, live-service cadence benchmark, Chinese game industry context. 언제 X: PvP-centric / esports / non-anime western RPG design.

❌ 안티패턴

• "miHoYo = HoYoverse": 매 같은 회사지만 매 China-only 운영은 mihoyo.com, global 은 hoyoverse.com 으로 entity 분리.
• "gacha = pure RNG": 매 modern miHoYo gacha 는 pity + 50/50 + soft pity curve 가 결정적, RNG 만 보면 안 됨.
• "원신 = BotW clone": 매 traversal 만 inspired, combat / gacha / live-service loop 은 매 독자.

🧪 검증 / 중복

• Verified (HoYoverse 공식 press kit, Sensor Tower 2024 mobile revenue report).
• 신뢰도 A.
