Image (executable)
An executable image is the final file for your game that’s ready to run. The executable image might also reference or use other files in the same directory, such as databases, graphics, or repositories.
You’ll likely create two different images
For a multiplayer game, you’ll probably have two images. The first is the client-side image (what the player will run). The second is the server-side image (what your server will run to host games). This second image is much more focused on game logic and transferring data back and forth between players.
