Mario Kart 7 used to be my favourite Mario Kart game for a long time and yeah, I can still see why. The controls feel just right (I'd argue that gliding feels way better here than in Mario Kart 8) and the track selection is really good.
I used to send cringe messages with this, it was great. I'm very glad I didn't have WhatsApp back then because god knows what stupid stuff I would have sent to so many other people...
