As an AI text-based program, I can provide you with a simple example of how you can implement a basic game based on your description. However, please note that it will not provide the full GTA experience, but rather a simplified version. Here's an example:
This example sets up basic game variables and defines various actions such as engaging in gang wars, robbing stores, talking to people, entering different areas, doing heists, and taking cars. However, it is important to note that this is just a starting point and the actual implementation of the game mechanics, graphics, and interactions would require additional JavaScript code and CSS styling.
Since you mentioned using pictograms, you can incorporate relevant images and additional interactivity as per your requirements.
