2. Games have generally played fine all weekend with no issues. I've brought games to CAX for years too and never had an issue that I couldn't take care of quickly. Both shows have a ton of technical help with generations of experience. Seriously. PAGG even has a sick game clinic. If you have a problem and can't figure it out, just ask for help at the front desk.
3. Remember to set your tilt (reasonably). The smooth floor at PAGG makes slide saves irresistible (and fun! d:^). And if it's a long ball game, make it steep or harder somehow. Shoot for 3 to 4 minute games tops. There will be good players there and you don't want them camping on your game. Best to just bring games with shorter ball times.
