I have attended TDA events every year I've attended gen con. Over the years I feel like the experience has slowly begun to fall short. Firstly, the amount of money you end up dropping on the event quickly gets out of hand. The ticket prices have climbed over the years, but I feel like that has not improved the experience. TDA started really when escape rooms were not a thing and expanded on the idea to start a successful micro transaction based gambling business. Not only do you find yourself gambling on the tokens you pull, but also on the quality of the puzzles and experience. Rather than explaining everything that happens during the event, check out their many videos online. I'll try to focus on a few parts that reduced my rating of this event. First, It's as dark as a movie theater during the entire event – to the point where you're using mini flashlights to be able to read or see anything. Yes, it's supposed to be a dungeon and darkness hides some stage effects, but I've seen this done much better in other escape rooms. Not to mention that every year I watch someone drop one of the potentially expensive tokens and it disappear on the dark floor. Second, someone is almost always disappointed about not getting to play a class they want. This year we had three folks wanting to play the Bard with no backup plan. Right out the gate two folks were upset. Third, it's high stress. You're rushed through puzzles and combat. I understand that time is a valuable asset when pushing people through the experience, but I'd gladly sacrifice two rooms to slow things down a little. Have backup bonus puzzles or combat if people finish early. Forth, the droning dungeon sounds used for noise cover up need to be rethought. I've also attended larger escape rooms who do not use this and it makes for a more enjoyable time where you can actually communicate without shouting. You also struggle to hear the pre-recorded dialogs or even an NPC/GM talking. It's fun once or twice, but I feel like long lasting players are going to start dropping off if things don't begin to change as ticket and token prices skyrocket.
