If you haven’t gotten any of the Crash games on Nintendo Switch, then you now have the chance, given that you live in the North and South America, Europe, Asia and Australia, to try out Crash Team Racing Nitro-Fueled in its entirety. This offer lasts between December 30, 2020 – January 5, 2021. It is unknown if this will be available for Japanese players.
You do need to be a subscriber of Nintendo Switch Online to try out the game via Nintendo’s own “Game Trials” initiative, similar to the Xbox trial of “Tony Hawk Pro Skater 1+2”.
