Most of the circuits provided in Mario Kart 8 Deluxe Pass Courses it seems to be taken directly from Mario Kart Tourwith the movable title representing the chapter of origin of all the tracks of the first run, arriving on 18 March 2022.
The question is partially known, but there are some interesting developments involving some discoveries made by dataminers recently, which show that even the tracks not originally belonging to Mario Kart Tour actually derive from the mobile chapter and have been transposed without major changes to Nintendo Switch.
As also reported by VGC, practically all the circuits of the first send, even those coming from the other previous chapters of the series, are in fact reworkings created for Mario Kart Tour and then transposed directly into Mario Kart 8 Deluxe, with some tricks minimum in terms of resolution and model building.
These are the tracks foreseen in the first batch of the Pass Percorsi del March 18, 2022as also reported in the details on the new tracks:
Golden Snap Trophy:
- Paris Promenade (Mario Kart Tour)
- Toad Circuit (Mario Kart 7)
- Cioccocanyon (Mario Kart 64)
- Cocco Outlet (Mario Kart Wii)
In addition to the three circuits taken directly from Mario Kart Tour, the others also seem to have been built for the latter, in fact they are reworkings of the originals but built to work in the mobile chapter: Cioccocanyon and Circuito di Toad have practically the same geometric setting and part of the assets of the mobile game, as well as Giardino Nuvola, which is expected to be introduced in Mario Kart Tour on February 23rd.
Outlet Cocco does not currently exist within Mario Kart Tour, but according to some datamines it should be introduced in the future, so it is likely that this is also taken from the mobile game. The only track with an unknown origin at the moment is Colli Mungo, even if the style could fall within that typical of the chapter for smartphones.
