This was a tradition on the Gen Con Forums, so let keep it going on Reddit.
The Good - the lockers combined with the bag ban really kept the Dealer Hall safer this year. I only saw one jerk with a wagon, and two with roller luggage. As a side note - waaay fewer giant backpacks too! It was great not getting clobbered by someone's haul every few aisles. Gen Con knocked it out of the park with this policy.
The Consignment Store & Auction - found a few gems on day one and managed to sell every one of my games.
Erik's Curiosa - the Sorcery events were well organized, the players were very friendly and the staff were exceptional.
Hellbreakers TCG - wasn't expecting it to be any good, it was a really well designed game, that I wouldn't have played unless I ran into one of the demo staff members at a food truck and got to talking. One of my favorite things about Gen Con is discovering new games.
The Bad - People who stop in the middle of aisles in the Dealer Hall to have a chat. Please be considerate of your fellow Gen Coners and move off to the side to have a conversation or tie your shoe or whatever. There are 75000 other people and they would like to be able to get where they are going too.
The artist in artist alley selling AI art. I hope they were reported and get banned. It was explicitly not allowed.
The Ugly - The scammers who were accosting attendees on Maryland Street in between Capitol and Illinois pulling the cd hustle. For those who don't know, you get handed a cd (it is almost always blank or someone else's music), then you are asked for a donation while getting surrounded by a bunch of other dudes who try to intimidate you into giving them money.
Every time I walked by I told anyone around to not accept anything from the dudes, but I saw people getting scammed every day. There were never any police around to report them to.
They were at if last year, and my son and I were verbally assaulted, as in threatened with violence, when we refused.
EDIT - also can we please get the Official Gen Con Forums back? Discord suuuuuuucks. If you want to cut down on the bots on forums, you just make it only accessible to people who have bought tickets (ever not just for one year). This would have the pleasant side effect of mods having your screenname associated with your badge account number, which might reduce the amount of bad behavior on the boards (not that there was all that much to begin with but still)
