Ultimate Simulation Game Template Development Plan

1. Player Mechanics

The goal here is to develop a smooth and immersive player experience.

First-Person Camera and Customizable Character Controller

Adjustable field of view (FOV)

Smooth movement with sprint, crouch, and jump mechanics

Dynamic head bobbing and camera shake effects for immersion

Controller and touch-input support for mobile


Health and Stamina System

Adjustable health/stamina recovery rates

Visual indicators (UI bars, screen effects when health drops)

Exhaustion and injury mechanics (e.g., reduced speed when tired)


Inventory System

Drag-and-drop interface for items

Categorization (e.g., tools, consumables)

Stackable items and weight-based limitations

Customizable item descriptions


Sleep and Time Progression System

Skip to the next morning when sleeping

Fatigue meter that encourages rest

Dreams or events during sleep to make it interactive




---

2. World Interaction Systems

Develop systems to allow players to interact with the world fluidly and meaningfully.

Interactable Props and Furniture System

Place, rotate, and interact with objects in the environment

Dynamic interaction hints (context-based prompts)

Ability to modify props (e.g., paint walls, rearrange furniture)


Readable Notes System

Scalable fonts and formatting

Save notes to inventory for later reading

Optional voice-over when notes are opened


Doors and Keys System

Locked doors that require keys or other items

Automatic or manual door opening animations

Sound effects and haptic feedback during interaction


Map System with Zoom In/Out Features

Interactive minimap and full-size map

Highlight task locations and important NPCs dynamically

Custom markers for players to place


Poster System for Wall Placement

Auto-alignment based on wall rotation and surface

Custom poster import and scaling options

In-game poster shop to buy more wall decorations




---

3. Simulation Mechanics

Provide deep simulation mechanics that allow players to engage with the environment.

Cleaning System

Cleaning dirt, graffiti, or debris from various surfaces

Different tools for different tasks (e.g., broom, mop, vacuum)

Progress tracker for cleaning goals


Building System

Modular building mechanics (e.g., floors, walls, roofs)

Placement grid system with snapping and alignment options

Building upgrades (e.g., stronger materials or additional rooms)


Repairing System

Tools such as hammers, screwdrivers, or wrenches

Repair minigames for immersive interaction

Deterioration system where items degrade over time


Task and Objective System

Multi-stage tasks with rewards upon completion

Optional hint system to help players progress

Task variety (fetch quests, timed challenges, puzzles)


Carryable Objects (Trash Bags, Boxes)

Adjustable object weight to affect movement

Physics-based interactions

Droppable anywhere on the map




---

4. NPC and Progression Systems

Create a vibrant, evolving world through dynamic NPCs and rewarding progression systems.

NPC System with Dialogue and Interaction

Custom dialogue trees with multiple choices

NPC schedules (move to different areas based on time of day)

Relationship system (build trust or reputation with NPCs)


Merchant System

Buy and sell items dynamically

Merchant stock updates based on player actions

In-game economy with changing prices


Reward System

Rewards tied to task completion and story progression

Unlockable items or abilities based on achievements

Leaderboards or progress trackers for competitive play


Dynamic Day-Night Cycle

Adjustable day length and lighting transitions

Impact gameplay (e.g., certain NPCs only appear at night)

Soundscape changes based on time of day




---

5. Environment Design and Optimization

Create a visually appealing environment with optimized performance for all platforms.

Town Area with Rotating Skybox

Dynamic weather system (rain, fog, clear skies)

Rotating skybox that reflects the time of day

Customizable landscapes (forests, mountains, beaches)


Pre-built Town Props

Low-poly assets optimized for mobile devices

Scalable buildings with modular designs

Seasonal decorations (e.g., snow, autumn leaves)


Outline System for Interactive Elements

Customizable outline colors for different objects

Dynamic outlines based on player proximity

Performance-friendly rendering for large scenes

How to Approach the Development Process?

1. Start with Player Mechanics:

Build the first-person camera, movement controls, and health system to ensure a solid foundation.



2. Develop World Interaction Systems:

Set up props, furniture, and doors to make the world interactive.



3. Implement Simulation Mechanics:

Add cleaning, building, and repairing systems to increase gameplay variety.



4. Focus on NPC and Progression Systems:

Introduce NPCs with schedules and a task system to drive engagement.



5. Design the Environment and Optimize Performance:

Create visually appealing landscapes and ensure smooth performance on all devices.

Key Features for Maximum Flexibility

Modular Systems: Every component should be reusable and easy to extend.

Cross-Platform Compatibility: Ensure the template runs smoothly on PC, consoles, and mobile.

User-Friendly Documentation: Include detailed setup guides for developers of all skill levels.

Customizability for Developers: Every element (UI, mechanics, environment) must be adjustable.
