I think we can all agree Mario Kart World needs to take notes from other games with superior track design. It's never a good look for a game with 8 whole years in the oven to get mogged by a game that only had nine months of development time by contrast.
Left: Nine months in development. Right: Eight years in development. What went wrong? Why did Mario Kart World fail where Sonic R so brilliantly succeeded?
Left: >game thrown together in nine months on a commercially unsuccessful console. Right: >game that had been in development for eight years as a launch title for the followup to a highly successful console. Why is this? Lack of effort? Different design philosophies?
