Car Lot

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a simple third-person 3D car-lot trading game titled “Car Lot.” Use a Three.js-like real-time 3D presentation with a perspective camera, soft blue-gray distance fog, directional sunlight, hemisphere fill lighting, shadows, and a dark charcoal 48x48 flat ground plane. The player is a minimal bright-blue capsule-shaped humanoid/walker, positioned near the front of the lot, with third-person movement and a camera that follows/looks around the character. Support WASD and arrow-key movement, mouse look, and touch-friendly virtual controls/joysticks on mobile if provided by the control system. The player can walk around the lot but there is no combat or driving mechanic.

Build the scene as a small dealership lot. At the rear, around z=-10, place a scaled-up low-poly city/shop building. In front of it, place a short horizontal strip/driveway made from repeated straight road tiles around z=5. Add simple fence sections along both side edges of the lot, approximately x=-9.5 and x=9.5, extending toward the building. Use low-poly stylized asset-pack vehicles with visible shadows and varied silhouettes/colors. Initially place four cars in a row across the lot around z=2: from left to right a Hatchback Sports at x=-7 priced at 
2,500, a Sedan Sports at x=-3 priced at 
5,800, a Sedan at x=1.5 priced at $9,800, and a Pickup Truck at x=5.5 priced at 
8,500. They are all initially for sale and rotated slightly.

Start the player with 
0,000. Add a fixed upper-left HUD over the 3D view: a large bold white “Money: 
0000” value (updating as transactions happen), with the smaller subtitle “Buy cars • Sell for profit.” Add a bottom-left instruction panel saying “WASD / arrows to move • Mouse to look • Click cars to buy or sell.” The visual style should be clean, sparse, low-poly and game-like, with dark translucent HUD panels, white/gray text, and a black/dark background beyond the fog.

Implement click interaction by raycasting from the mouse/touch pointer into the scene and identifying clicked car models, including clicks on any child mesh of a car. When a for-sale car is clicked and the player has enough money, subtract its listed price, mark it owned, move it to a garage/display area on the right side around x=7 plus 2.8 units per already-owned car and z=-1, rotate it to face a different direction, and show a temporary green toast such as “Bought Hatchback Sports for 
2500.” If the player cannot afford it, do not move it and show “Not enough money!” If an owned car is clicked, sell it for exactly floor(original price * 1.65), remove it from the scene, add that amount to money, and show a temporary toast such as “Sold Hatchback Sports for 
0625 (+$8125).” Maintain the count/state of for-sale and owned cars, and update the HUD immediately after every transaction. Use a short-lived centered-bottom dark toast notification for transaction feedback. Keep the implementation focused on this single buy/sell loop and the walkable dealership environment; do not add missions, traffic, enemies, inventory screens, or extra gameplay systems not described here.
