This is a great overview of 3-tier architecture! It really clarifies how separating the presentation, application, and data tiers can improve scalability and maintainability. Thinking about it, the presentation tier is like the user interface of a game - imagine something like Drift Hunters, where you need a responsive and engaging visual experience. The application tier handles the game logic, and the data tier stores all the car stats and track info. A well-defined 3-tier structure is essential for robust software design, especially for complex applications.
