I'm not arguing whether it's good prices with you. I'm just pointing out that you claimed Power Play is "literally" the cheapest arcade in Washington State. That just isn't true. Despite what some Seattle folks might like to assume, the state consists of more than just King County. There's arcades in Spokane and Pullman that're just as cheap, if not cheaper to play at.
It might not be expensive to play Pump it Up at Power Play, but last time I visited, Guitar Hero and some of the other games cost $1 per play. If you had claimed that Power Play is the cheapest place to play Pump it Up in King County, I probably wouldn't be arguing with you now, because it could be the factual truth. I'm merely saying there's a lot of equally, or less expensive arcades in Washington State and it's a personal peeve of mine when someone makes statements about something being "the literal best _____ in _____" and it's not the truth.
At this point, I'm sure any reader knows what we're both getting at. You're right that Power Play isn't nearly as expensive as other arcades in the area. And I've pointed out that there's plenty of cheap arcades outside of King County that people can play games at.
