Every M1 race from the 2019 season. Picked a team during the intro and found myself rooting for this crazy marble that put it all out there race after race battling to a 3rd place season finish.

Surprisingly intense competition. It's cool all the physics and variables and funny interactions that determine the outcomes of these races. Great announcer. Awesome tracks. The love that goes into creating this thing too.
I heard about this watching a John Oliver segment last night who spotlighted it. There wasn't going to be a next season until he stepped in as a sponsor. 2020 season kicks off in June.
