# Power Creep (Content Treadmills)

## 매 한 줄
> **"매 power creep은 매 live service game의 매 매 patch마다 매 new content를 매 'previous content보다 strong하게' 만드는 매 design pressure — 매 player engagement(매 chase)는 자극하지만 매 long-term 매 trivializes 모든 prior content."** Diablo 3, WoW, Genshin Impact, Marvel Snap, Honkai Star Rail, 매 매 gacha game 모두 매 power creep 의 매 victim 또는 매 deliberate user. 매 2026 시점, miHoYo / HoYoverse가 매 'sideways power creep' (매 vertical inflation 대신 매 horizontal team comp shift)으로 매 partial mitigation.

## 매 핵심

### 매 power creep mechanism
- **Engagement loop**: 매 new banner / patch → 매 previous BIS (Best In Slot) inferior → 매 player FOMO → 매 monetization spike.
- **Content trivialization**: 매 old raid / dungeon이 매 new gear로 매 1-shot → 매 historical content 가치 0.
- **New player hostility**: 매 entry barrier가 매 매 patch마다 raise → 매 mid-game player retention 어려움.
- **Veteran burnout**: 매 매 grind reset이 매 매 patch마다 → 매 'I just got BIS, now obsolete'.

### 매 mitigation 전략
- **Sideways creep (Genshin / HSR)**: 매 new character가 매 power 'up' 아니라 매 new team comp niche.
- **Periodic reset (Diablo Seasons)**: 매 매 3-month season → 매 모든 player 매 0부터 → 매 power creep 매 contained.
- **Gear sidegrade (Destiny 2 perks)**: 매 raw stat 매 stable, 매 perk synergy로 매 differentiation.
- **Soft level cap (FFXIV)**: 매 expansion마다 매 cap raise + 매 old gear 자동 sync — 매 old raid 다시 challenging.
- **Power band compression (LoL champion balance)**: 매 매 patch마다 매 outlier nerf + 매 underperformer buff — 매 매 champion이 매 viable band 안에.

### 매 응용
1. **Genshin 매 Hyperbloom meta (2022)**: 매 dendro element 도입이 매 raw stat 아닌 매 reaction system 변경 → 매 새 team archetype 생성, 매 old characters (Xingqiu, Fischl) 매 다시 valuable.
2. **Marvel Snap 매 OTA balance (2024)**: 매 'Over The Air' patch — 매 매 2주 매 outlier card buff/nerf, 매 매 deck cycle 빠름.
3. **WoW Classic Hardcore (2023)**: 매 power creep 거부 — 매 vanilla 그대로 → 매 nostalgia + 매 deathless run engagement.

## 💻 패턴

### Power band tracking
```python
import pandas as pd
import numpy as np

def measure_power_creep(patch_history: pd.DataFrame) -> pd.DataFrame:
    """
    매 patch별 매 release item의 매 average power score를 plot.
    매 power score는 매 (DPS_simulation + utility_score) / item_level.
    """
    by_patch = patch_history.groupby('patch_id').agg(
        avg_power=('power_score', 'mean'),
        max_power=('power_score', 'max'),
        n_items=('item_id', 'count'),
    )
    by_patch['creep_pct'] = by_patch['avg_power'].pct_change() * 100
    return by_patch

# 매 healthy: creep_pct < 5% per patch
# 매 unhealthy: creep_pct > 15% per patch (Diablo 3 vanilla 식)
```

### Sideways creep — niche team comp validator
```python
def is_sideways_release(new_char: dict, existing_meta: list[dict]) -> bool:
    """
    매 new character가 매 existing top-N comp에 매 'replace existing strong' 하면 vertical creep.
    매 'enables new comp not previously viable' 하면 sideways.
    """
    enables_new = []
    replaces_existing = []
    for comp in existing_meta:
        sim_score_old = simulate(comp)
        for slot in comp['slots']:
            new_comp = comp.copy()
            new_comp['slots'][slot] = new_char
            sim_score_new = simulate(new_comp)
            if sim_score_new > sim_score_old * 1.1:
                replaces_existing.append((comp, slot))
    new_comps = generate_comps_with_required(new_char)
    enables_new = [c for c in new_comps if simulate(c) > comp_threshold]
    return len(enables_new) > len(replaces_existing)
```

### Seasonal reset (Diablo Seasons style)
```python
class SeasonReset:
    def __init__(self, duration_days=90):
        self.duration_days = duration_days
        self.start_date = None

    def start_season(self, season_id: int, balance_adjustments: dict):
        self.start_date = datetime.now()
        # 매 모든 seasonal player → 매 fresh char
        for player in get_seasonal_players():
            create_fresh_character(player, season_id)
        apply_balance(balance_adjustments)

    def end_season(self):
        # 매 seasonal char → 매 non-seasonal로 migrate
        for char in get_seasonal_chars():
            migrate_to_eternal(char)
```

### Soft cap with auto-sync (FFXIV style)
```python
def auto_sync_gear(player_ilvl: int, content_ilvl: int) -> int:
    """
    매 player ilvl > content ilvl 이면 매 sync down.
    """
    return min(player_ilvl, content_ilvl)

# 매 ARR (2.0) raid를 매 Endwalker 6.5 player가 즐길 때 매 ilvl 110으로 sync → 매 challenge 유지
```

### OTA balance hot-fix
```python
# 매 backend balance — 매 client patch 없이 매 매 buff/nerf
balance_data = {
    'card_silver_surfer': { 'cost': 3, 'power': 4 }, # 4 → 3
    'card_zabu':          { 'cost': 1, 'power': 2 },
    'patch_version': 'OTA_2026_05_08',
}
# 매 client는 매 launch 시 매 server에서 매 latest balance fetch
def fetch_balance():
    return requests.get(f'{API}/balance').json()
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| Gacha live service | Sideways creep (Genshin 식) |
| ARPG / Diablo-like | Periodic season reset |
| MMO with vertical progression | Soft cap + sync (FFXIV) |
| Card game | OTA balance (Marvel Snap) |
| Hardcore PvP | Tight power band (LoL) |

**기본값**: 매 sideways or seasonal reset. 매 pure vertical infinite creep은 매 5년 안에 매 game collapse.

## 🔗 Graph
- 부모: [[Game-Balancing]]

## 🤖 LLM 활용
**언제**: 매 LLM에게 매 historical patch power score 분석 + 매 power band drift 시각화 요청.
**언제 X**: 매 actual balance number tuning — 매 simulation은 매 player metagame를 fully predict 못 함.

## ❌ 안티패턴
- **Vertical-only creep**: 매 매 patch마다 매 raw stat +10% — 매 5 patch 후 매 collapse.
- **Mandatory new gear**: 매 old gear 매 immediate obsolete → 매 player feels treadmill.
- **No content sync**: 매 old raid / dungeon이 매 trivial → 매 historical content 매 dead.
- **Hidden creep**: 매 patch note에 매 power increase 안 명시 → 매 player trust loss.
