From GameWatcher: “Even if RollerCoaster Tycoon 3 hasnt aged as gracefully as its predecessors, theres plenty of fun to be had. If you still have the original and can run it fine, you dont need to buy it again. But if youre someone who never got to play it, cant run Planet Coaster, and miss the old school approach to the Tycoon genre, the Complete Edition is a neat relic to a bygone era of gaming. Just be prepared for some outdated features and a shockingly small UI.”
