I'm a little disappointed with Mario Kart World and here's why.

Adding on to @BowserJr03's research, Mario Kart World was still being developed in 2017, and I know they've been working on the Free Roam and a lot a details for about 6 years in development. So, to add this up, they wanted more of the world gimmick, not another, random, new gimmick. Also, I'm pretty sure there won't be another game like MKWorld for a while, just think how long it'll take for a story mode, another free roam, a bigger cast, and foods compatible with every character.
Here's a console prediction for the next one:

Heres one final also, @GamerJax55, stop complaining about how Mario Kart World has almost nothing in MK8DX. MK8DX is a piece of garbage, but yet still good. Be thankful Nintendo is still making games and one of the main developers didn't die or something.
