RollerCoaster Tycoon was programmed mostly entirely in x86 Assembly because it offers direct control over hardware resources, allowing for efficient and optimized coding. Assembly language provides low-level access to the computer's processor, registers, and memory, enabling the programmers to fine-tune the performance and take full advantage of the system's capabilities. This level of control was essential for implementing the complex and highly interactive gameplay mechanics, intricate simulations, and real-time graphics required by the game, making x86 Assembly the ideal choice for achieving the desired performance and responsiveness.
