This day and age really surprises me how we are all connected using the internet, but also at the same time don't know anything and years go by without being the wiser. It's true that they're no other kart racing game quite like MarioKart on the market right now. Look at sales since it released and what it has sold on. The game has outsold the PS4 on a dying system, but publishers, developers, and even you VGChartz forum dwellers can't seem understand the power of a good kart racer.
a good arcade racer especially a kart racer is an instant buy to casuals and non casuals when they get a console.
