|
|
|
## Project Overview
|
|
|
|
This project aims to recreate and modernize the beloved Palm OS game "Space Trader" (2002) - a complex trading and economic simulation game inspired by the classic space game "Elite" but without the flight simulation component.
|
|
|
|
### Original Game
|
|
|
|
Space Trader is a freeware game where players navigate a procedurally generated universe, trading commodities between star systems to accumulate wealth, with the ultimate goal of purchasing a moon and retiring in luxury.
|
|
|
|
**Reference Implementation:** [Space Trader for Android by Russell Wolf](https://bitbucket.org/brucelet/space-trader/src/master/)
|
|

|
|
|
|
## Core Game Mechanics
|
|
|
|
### 1. Trading System
|
|
- **10 different commodities** traded across multiple star systems
|
|
- Prices dynamically determined by:
|
|
- System's technological level
|
|
- Political system
|
|
- Random events (shortages, surpluses, wars, etc.)
|
|
- Economy simulation with supply/demand mechanics
|
|
|
|
### 2. Space Travel & Encounters
|
|
- Travel between interconnected star systems
|
|
- Random encounters during travel:
|
|
- **Police** - Inspect cargo, enforce laws
|
|
- **Traders** - Potential trade or interaction
|
|
- **Pirates** - Combat or flee
|
|
- Special rare encounters (famous captains, aliens, unique items)
|
|
|
|
### 3. Ship Management
|
|
- **10 different ship types** varying in:
|
|
- Cargo capacity
|
|
- Speed/fuel efficiency
|
|
- Weapons/shields capacity
|
|
- Hull strength
|
|
- Upgradeable equipment:
|
|
- Cargo bays
|
|
- Weapons systems
|
|
- Shields
|
|
- Special gadgets
|
|
|
|
### 4. Reputation & Alignment
|
|
- **Police Record** - Lawful to criminal
|
|
- **Reputation** - Fame/notoriety
|
|
- Actions affect future encounters and opportunities
|
|
- Multiple playstyles supported:
|
|
- Pure trader (legal goods only)
|
|
- Bounty hunter (hunt pirates)
|
|
- Pirate (attack traders, evade police)
|
|
- Mixed approach
|
|
|
|
### 5. Economic Progression
|
|
- Start with small ship and limited credits
|
|
- Gradually upgrade to larger vessels
|
|
- Invest in equipment and cargo capacity
|
|
- **End goal:** Accumulate enough wealth to purchase a moon and retire

|
|
**Total Estimated Time:** 19-25 weeks (4.5-6 months) for a single developer
|
|
|
|
### Complexity Factors:
|
|
|
|
#### High Complexity Components:
|
|
1. **Economic Simulation** - Dynamic pricing with multiple variables
|
|
2. **Procedural Generation** - Consistent, balanced galaxy generation
|
|
3. **AI Systems** - Different behaviors for police, traders, pirates
|
|
4. **Combat System** - Turn-based or real-time mechanics with equipment factors
|
|
5. **Balance** - Ensuring fair progression and challenging gameplay
|
|
|
|
#### Medium Complexity Components:
|
|
1. **Save/Load System** - State persistence
|
|
2. **Event System** - Random events affecting markets
|
|
3. **Reputation System** - Tracking player actions and consequences
|
|
4. **Ship Management** - Upgrades and equipment
|
|
|
|
#### Lower Complexity Components:

3. **UI Framework** - Menus and screens
|
|
4. **Galaxy Map** - Navigation interface
|
|
|
|
### Technical Challenges:
|
|
|
|
1. **Balancing Act** - Economy must be engaging but not exploitable
|
|
2. **Performance** - Large galaxy with many systems and calculations
|
|
3. **Replayability** - Procedural generation must create varied experiences
|
|
4. **Save System** - Handling complex game state
|
|
5. **AI Behavior** - Making encounters feel intelligent and fair
|

|
## Technology Considerations
|
|
|
|
### Platform Options:
|
|
1. **Web-based** (JavaScript/TypeScript + HTML5 Canvas)
|
|
- Pros: Cross-platform, easy distribution, no installation
|
|
- Cons: Performance constraints for large simulations
|
|
|
|
2. **Desktop** (Python + Pygame, or C#/Unity, or Godot)
|
|
- Pros: Better performance, native feel
|
|
- Cons: Platform-specific builds needed
|
|
|
|
3. **Mobile** (React Native, Flutter, or native Android/iOS)
|
|
- Pros: True to original platform, portable
|
|
- Cons: Touch interface design, multiple platforms
|
|
|
|
### Recommended Approach:
|
|
**Start with Web-based prototype** using TypeScript/JavaScript:
|
|
- Rapid development and iteration
|
|
- Easy testing and sharing
|
|
- Can be ported to desktop/mobile later
|
|
- Modern web tech handles game complexity well
