- RollerCoaster Tycoon (1999) is praised for its optimization, written almost entirely in Assembly by Chris Sawyer.
- The game's performance was achieved through aggressive optimization, including fine-grained data type usage for money values.
- Math operations were optimized using bitshifting instead of traditional multiplication and division.
- Game design decisions, like simplified pathfinding for guests, were made with performance in mind.
- Guests in RCT don't collide or avoid each other, reducing computational overhead while still simulating overcrowding effects.
- The pathfinding system has built-in limits to prevent performance spikes, with adjustable limits for different agent types.
- RCT's optimizations were possible due to Chris Sawyer's dual role as programmer and game designer.
- Modern game development could benefit from similar design-for-performance approaches, though it requires close collaboration between designers and programmers.
