Street Fighter 6

Well, if you're really good at this game you might unlock this at the same time as There's Always Time for Training! (40G) but likely you'll need to play a few more - win 30 total matches in the Battle Hub for this achievement by sitting down at one of the two-sided arcade machines and waiting for someone to challenge you, or find a machine with someone already sitting at it and challenge them. If you can find a friend to boost with, you can have them stand still and keep challenging each other in an empty server to get this done extremely quickly.
