Happy birthday to you as well! Yeah I find is hilarious they give Gold Knight his own exclusive tracks, TWO tracks, in RANKED for the second week just to tease us… just wow lol!
First of all, Happy Birthday! Luigi Circuit is so good, Waluigi Circuit is just as great as ever (while I like also the 8 Deluxe version, it's nice to have something closer to the original and Wii for Tour) and I personally don't mind Mario Raceway, although I definitely agree that it's the weakest of these tracks!
I really loved playing Waluigi Stadium, I like the tour version better than MK8. The item boxes are placed better, the piranha plants are in the correct spot, and the skybox looks more like the OG version. Oh, also there are more boost panels on the ramps! Happy Late Birthday!!
