CAR GAME Modification in VB.NET and Truevision 3D SDK Phase 1

We have very basic 3D Car simulation Game done in VB.NET and Truevision 3D SDK. Now we want to develop this game as follows; 1. Main Menu to choose options. 2. Weather : FOG, RAIN, DRIZZLING 3. NIGHT DRIVE with Road with Lamp posts, Moon light, Dark road with head light. 4. City is already there nicely. But we need to change and make some parking area. Like in the market. 2 Parking. 1 Busy parking, 2 less busy parking. 5. Two option form the main menu : a. Lots of traffic (moving vehicle) b. Less traffic (moving vehicle). Like different kind if cars, buses. You may use sample models from the web. 6. City Roads are already there with two lane divider. But we need speed brake bumps. The usual single bumps we find near the schools and road crossing. 7. Important : Totally new part will be off the road driving. Like a field with trees etc. Same in night time drive. 8. Each session the game will generate a text file with all the mistakes, bumps and bashes, red light violation etc.
