A number of solid state games were well below par if not unplayable. My wife and I only played the following games that were without issue.
WOZ, Stranger Things, Centaur, Rollergames, Memory Lane, Quicksilver, R&B and 4MBC.
Largest issue seemed to be dead, weak or broken flippers but we played several games that had electrical issues or saw games with obvious signs of distress like a Buck Roger's that the displays were on but the playfield was dead.
And we were there early when the doors opened at noon so everything wasn't beat to death yet. You always get a few games that will break down during a show, this year was a very high number though and some of them had pretty stout prices on them.
Lines for Mandalorian and Ultraman were long, people seemed to like them, vendors had brisk traffic.
