As a small group EO (26 RPG events/156 tickets), it was nice to not have to play the yellow envelope game. That was nice.
However we did have a fair amount of difficulty scanning badges, to the point where at one point we had to stop trying to scan the badges as we were eating into game time, getting only 10 of 18 badges to properly scan. I spoke with the HQ table the following day and got a few tips on scanning that helped, though did not completely alleviate the trouble we had.
What we liked:
Every e-ticket game my friend or I attended had issues where the gamemaster could not get at least a few badges to scan at all, despite seeing the players were registered. Apparently the Discord was no help in solving this issue, though that is third-hand information on my part certainly. I do know my friend who had this problem at every game he attended has declared he is never coming back, though I think this is only a small part of the issue.
I spoke with the GenCon e-ticketing expert (sadly, I forget his name, but he was very helpful) and we noted that the bar codes were smaller this year. I think this had something to do with not being able to consistently read them. I had many of the same errors on my android phone, but my iPad managed to read them without much trouble.
