I played in all four games. I had a great time. The content was great, the sessions were smoothly run, and all the DMs and players I interacted with were great.
The best story I have is one of sessions a 1st level character got insta-splatted for 30some points of damage (after which the rest of the party avoided the monster). At some point, players were reflecting on which modules were the hardest; the common example was Silken Caravan, but we were like,
So we ended up figuring out that the DM had sent the tier 4-5 creature at us. It all got smoothed out a couple days later after we discovered what happened. :)
I'm looking forward to more scenarios. :)
