As players work to build their dream parks, whether they choose Sandbox, Challenge, or Career mode, they may notice a similar problem crop up: park employees become dissatisfied, either from boredom or stress. Created by Frontier, the game allows a high level of customization that allows the player to build a theme park any way they want. Planet Coaster is the spiritual sequel to the wildly popular Rollercoaster Tycoon. While many popular amusement parks, like Disneyland and Universal Studios, remain closed for the summer, players can still experience the magic and thrill of theme parks by creating their own in Planet Coaster.
