I’ve been up here to visit friends a few times. There may not be a Round 1 but there are a few places with rhythm games around the Twin Cities with a friendly community.

Arcades (info taken from the linked Discord, check there for most up to date info):
Starcade St Paul - Sound Voltex, Chunithm, ITG and Groove Coaster, all online. GFDM coming soon? There’s also a great selection of fighting games and a sick Virtual On setup. Definitely the arcade to go to in MN.
