My wife and I were there for most of Saturday / Sunday and had a blast.
The biggest compliment I can give the team is that it felt like an event that's been going on for years. Getting our tickets was smooth, finding food and drink was easy, and there was almost always a game available within 20 feet of anywhere on the floor.
I can't speak much to the condition of the EMs much (although El Toro was my game during the Guinness world record ), but I got a ton of play on the DMD and SS games. It was really nice having many machines from the same era in the same area...it's fun to get a feeling for how similar a lot of the scoring, rules and sound effects were for each manufacturer...it's an obvious thing, but fun when everything is side-by-side.
We'll definitely be back!
