If you enjoy the Isometric view of the original RCT titles, but wondered if it was made 20 years later? Parkitect is the park sim for you. It features new aspects of park management with decoration and haulers. You don't want guests to see back stage (bad decoration). Like in Planet Coaster, they also like rides with high decoration rating. Because of the above, their are new challenges in the 20+ campaign levels.
It is $30 on Steam.
