| Goal | Success Metric | |------|-----------------| | Narrative Depth – Reinforce Kira Lia’s personality and story arcs through a believable “drunk” condition. | Player surveys show ≥ 80 % feel the drunk state adds to immersion. | | Gameplay Variety – Offer new tactical options and risk/reward decisions. | Average session time ↑ 10 % when drunk‑state encounters are present. | | Accessibility – Provide clear visual/audio cues and optional mitigations for players who prefer to avoid the effect. | Accessibility rating ≥ 4.5/5 in internal testing. | | Balance – Ensure the drunk state is neither a guaranteed win nor a guaranteed loss. | Win‑loss ratio for drunk‑state runs stays within 45‑55 % across skill tiers. |
| Risk | Probability | Impact | Mitigation | |------|-------------|--------|------------| | Performance hit on low‑end PCs | Medium | Medium | Provide quality‑setting toggle to disable post‑process effects. | | Negative perception of alcohol portrayal | Low | High | Include clear content warning, optional disabling of the entire system, and a “sober‑only” mode. | | Complexity of stat stacking | Low | Medium | Unit‑test all possible modifier combinations; use deterministic order (base → intox → buffs → debuffs). | | Player frustration from blackout loss | Medium | Medium | Offer “Hangover” recovery items and make blackout a rare, not guaranteed, outcome. | Kira Lia Drunk
| Narrative Hook | Example Implementation | |----------------|------------------------| | Story‑Driven Drinking | In Chapter 3, Kira Lia attends a tavern celebration. Player may choose to drink (triggering the system) or stay sober, branching into two different story beats. | | Character Development | NPCs comment on her “spirited” behavior; repeated drunkenness unlocks a personal quest line about confronting past trauma. | | World‑Building | Certain secret areas are only accessible when Kira Lia is drunk (e.g., a hidden door that reacts to her slurred speech). | | Moral Choices | Players can decide to drink to gain a temporary advantage at the cost of possible blackout and loss of items, emphasizing risk/reward. | | Goal | Success Metric | |------|-----------------| |
| Mechanic | Description | Implementation Details |
|----------|-------------|------------------------|
| Intoxication Meter | A semi‑circular UI element around the health bar that fills as Kira Lia drinks. | - 0 % = sober. - 100 % = fully drunk (max effect). - Meter decays at a rate of 5 %/sec when not drinking, faster (8 %/sec) if the player activates “Water Break”. |
| Stat Modifiers | Intoxication alters core stats: | - Accuracy: ± (−10 % × %Intox) → 10 % penalty at full. - Movement Speed: + (5 % × %Intox) → 5 % boost at full (slightly “lighter”). - Reaction Time: + (30 % × %Intox) → 30 % slower at full. - Luck: + (15 % × %Intox) → increased critical hit chance. |
| Perception Distortion | Visual & auditory filters simulate drunkenness. | - Blur/Edge‑Detection: 0 % → 25 % screen blur at full. - Color Shift: Warm hue saturation ↑ 15 % at full. - Audio Reverb: Slight echo on ambient sounds; dialogue muffles proportionally. |
| Control “Wobble” | Subtle, random input drift to emulate impaired coordination. | - Input vector offset generated via low‑frequency Perlin noise, magnitude = 0.05 × %Intox of stick deflection. |
| Dialogue Variants | NPCs react to Kira Lia’s drunkenness with alternate lines and optional “drunk‑only” quests. | - Dialogue tree nodes flagged DRUNK_ONLY. - NPCs may offer “drink‑related” side‑quests (e.g., “Find the lost bottle”). |
| Risk/Reward Interaction | Certain gameplay systems (e.g., lock‑picking, gambling, combat) have modified success curves. | - Lock‑Pick: Base success × (1 − %Intox) + (Luck × %Intox). - Gambling Mini‑Game: Payout multiplier ↑ (0.5 × %Intox). - Combat: Damage dealt ↑ (0.2 × %Intox) but chance to miss ↑ (0.4 × %Intox). |
| Recovery Options | Players can mitigate intoxication via items or actions. | - Water: Instant -30 % meter, +10 % movement speed for 5 s. - Coffee: -50 % meter, temporarily restores reaction time (adds “clear‑head” buff for 8 s). |
| Failure State – “Blackout” | If the meter reaches 100 % and a high‑stress trigger occurs (e.g., taking damage > 20 % max HP), Kira Lia may blackout. | - Cutscene: Fade to black, player loses control for 2‑4 s. - Consequence: Random loss of an inventory item (selected from “non‑essential” pool) and a temporary debuff “Hangover” (‑10 % all stats for 30 s). | | Risk | Probability | Impact | Mitigation
