"Theme Park" offers three levels of simulation: the higher difficulties requiring more management of aspects such as logistics. For example, at full level, the player must manage research, negotiations, stocks, and shares. On sandbox, the game does not involve those aspects. The player can switch mode at any time. Game time is implemented like a calendar: at the end of each year, the player is judged on that year's performance against rivals. Game speed can be adjusted, and staff can be moved by the player. Cash awards may be earned for doing well, and trophies may be awarded for achievements such as having the longest roller coaster.
