Played through the Abyssal Swamp and the Path of Death at Gen Con 2019. While our group had fun in both rooms, we had some issues with the set up that we thought could be fixed with some minor tweaks. Granted, this was our first time with True Dungeon, but I hope our ideas have some merit.
1.) Difficulty selection - in the Swamp, the person filling out the party card asked 1 person what difficulty was being played, and went with what that person answered, without discussing it with the rest of the group. In the Path, 5 of 10 people (my group) were new players. The other 5 had been playing for 10+ years. The other 5 pushed for Hardcore, which our group wasn't ready for and one of our players ended up dead because of it.
Our suggested fix: base difficulty on time slot. That way, more advanced players can buy hardcore or higher tickets, and less advanced players can buy normal or non-lethal time slots.
2.) Player imbalance - as mentioned before, in Path, we had 5 newbies and 5 advanced players. So our 5 players walked in with the tokens we got that day, and a few basic 10 packs that we bought before going to Gen Con to try to prepare. The 5 advanced players in the group had thousands of dollars worth of tokens, with some individual tokens worth $1,000+ that they have collected over the years. This lead to some of the advanced players replacing our players entire loadouts with their tokens because our stuff was inadequate.
We think the same fix as before would work. Players with better gear could go to higher difficulty levels, and new players could stay on the lower levels.
Just a thought.
