The "RollerCoaster Tycoon" video game involves creating rollercoaster tracks that optimize for various game metrics while also being constrained by the need to ensure a feasible structure in terms of physical and spatial bounds. Creating these procedurally is thus a challenge. In this work, we explore multiple approaches to rollercoaster track generation through the use of Markov chains and various deep learning methods. We show that we can achieve relatively good tracks in terms of the game's measurement of success, and that reinforcement learning allows for more control of the generated tracks and for different rider experiences. A focus on multiple measures allows our work to extend to other track properties drawn from real-world research. This paper extends a previous publication by adding a new reward function for our reinforcement learning agent as well as further analyses of the generated tracks, including a metric measuring rider excitement over time, a revised novelty metric and an analysis of controllability.
