# RR3 Community Server - Complete Game Systems Implementation

## 🎮 NEW: Full Game Progression System

Based on analysis of the decompiled RR3 APK, I've implemented a comprehensive progression system that mirrors the actual game structure.

## ✅ What's Been Added

### 🏎️ Car Ownership & Garage System
- **Purchase cars** with Gold or Cash
- **5 starter cars** across all classes (C, B, A, S, R)
- **Car database** with manufacturers, performance ratings, pricing
- **Garage management** - track all owned vehicles
- Full inventory system for player garages

### ⬆️ Car Upgrade System
- **5 upgrade types**: Engine, Tires, Suspension, Brakes, Drivetrain
- **Progressive upgrades** - increase Performance Rating (PR)
- **Cash-based economy** for upgrades
- **Upgrade tracking** per vehicle
- Performance improvements visible immediately

### 📈 Player Progression & Leveling
- **Experience Points (XP)** - earn through racing
- **Level system** - gain levels every 1000 XP
- **Level-up rewards** - 10 Gold + 5,000 Cash per level
- **Reputation system** - track player standing
- **Currency tracking** - Gold, Cash, XP, Reputation

### 🏁 Career Mode Support
- **Career series tracking** - organize events by series
- **Event completion** with star ratings (1-3 stars)
- **Best time tracking** per event
- **Star-based rewards**:
  - 10 Gold per star
  - 2,000 Cash per star
  - 100 XP per star
- **Progress persistence** - resume where you left off
