"Create a high-quality 3D car racing game featuring multiple car models, dynamic environments (such as city roads, highways, and off-road tracks), and realistic physics. The game should include different game modes (like time trial, multiplayer, and tournament), sound effects, smooth controls (keyboard/controller compatible), and a leaderboard system. Add nitro boosts, drifting mechanics, and obstacles like traffic and weather effects (rain, fog). The UI should be modern and user-friendly. The theme should be fast-paced and exciting, similar to games like Need for Speed or Asphalt 9."
