Vanilla But Wrong
A psychological horror Fabric mod for Minecraft 1.21.1 where your mind is shared, your safety is temporary, and the game keeps watching you.
One sanity value. All players. If one player slips, everyone pays.
What This Mod Is
But Vanilla is Wrong transforms survival into a pressure system built around shared sanity, environmental stress, trauma progression, adaptive events, and unsettling UI/audio distortion.
This is not a jumpscare-only mod. It is a long-form tension mod that changes how you move, mine, fight, and plan.
Core Gameplay Loop
- The server has a global shared sanity pool.
- Sanity drains over time and reacts to danger context.
- Hunger, darkness, weather, biome pressure, and dimension context can accelerate decay.
- Low sanity unlocks stronger Director events and heavier psychological effects.
- Death adds trauma that permanently weakens long-term stability until treated.
Major Systems
Shared Sanity (Hivemind)
- One sanity value is used by all players.
- Environmental and combat stress push everyone closer to collapse.
- Recovery is possible, but mistakes are global.
Director Event System
- Context-aware intrusions trigger based on sanity phase and behavior.
- Event priority and lock rules prevent chaotic overlap.
- Critical phases escalate to severe event sets.
- Execution states hard-lock lower events for cleaner pacing.
Psychological Effects
- Dynamic sanity HUD with live phase feedback.
- Visual corruption across game UI at low sanity.
- Menu/button instability effects.
- Tooltip and interface degradation.
- Audio distortion and pressure cues that intensify with risk.
Trauma Progression
- Dying adds trauma stacks.
- Trauma lowers effective max sanity cap and increases long-term pressure.
- Death can also apply lasting body penalties.
- Recovery requires effort and resource planning.
Medicines
- Sanity Pills for mental stabilization.
- Trauma Medicine to reduce trauma progression.
- First-join horror manual includes recipe guidance and survival logic.
First-Join Horror Manual
- New players receive an in-world written manual.
- It explains core mechanics in layered, horror-style notes.
- Includes medicine crafting formulas and practical warning cues.
Multiplayer Design
- Built to feel fair but oppressive in co-op.
- Join/respawn handling includes sanity-system grace windows.
- Session/world boundary handling is designed to avoid cross-world state contamination.
- New players are synced into current world pressure without breaking progression flow.
Balance Goals (1.1.0 Era)
- Low-sanity range uses controlled pacing to avoid instant unfair wipes.
- Extreme launch/fall event outcomes are safety-limited.
- Passive encounter audio and event readability are cleaner.
- Book/UI readability improved while keeping horror identity.
