What Lloyd said.
We also have a roaming team of technicians to work on any games that experience issues while on the floor. We use a keyboard system that corresponds to a number on each game so we can quickly fix them if something goes wrong. We also have incentives to bring games such as cash prizes for best in show for each style game along with giving a full show pass for each game someone brings to the show. I brought my nearly mint Whitewater last year and it got almost 1250 plays over four days. It needed a quick shop job afterward but people were happy to play it and that's what made me happy.
As for the line-up, well we post what people say they are bringing but it's always subject to change, things sometimes fall through in peoples plans.
Either way, we hope to see you there!
