My brother and I did one room at Escape Game SD in San Diego, California. The room was called Superheroes Adventure, but my primary thoughts about this location are about everything that happened before and after the room.
In order to access this location, we had to walk down an alley into a scary parking lot, up an obscure stair case, and into a door that has too little signage. When we got into the building, there wasn't anyone there to greet us, and we wandered into some kind of break room to looking for someone. When the game master finally appeared out of nowhere, she was very nice, but seemed like she was having a hard time keeping up with her tasks even though we were the only people there.
Mike's Difficulty Rating: 2 (out of 5)
Their Difficulty Rating: Challenging (as apposed to Moderate)
The puzzles were primarily generation one (traditional) locks, but I did appreciate that the puzzles seemed to fit with the theme. The game master made the game more fun because it felt like she was enjoying the room with us. I noticed that because game masters in other rooms often seem uninterested and annoyed.
