Caleb's world building is on another level, he always had answer and everywhere my character wanted to go, there was something for her to do or interact with. His game felt like a healthy balance of open world style, with enough structure to the NPCs and clues, that you also have several clear paths forward to your objective. He's patient, entertaining and does well playing as his NPCs as they would act, as well as combining great voices and impeccably timed background music during both combat and roleplay. If you're looking for a refreshing experience with a DM that loves the game and will collaborate with you on what you want to accomplish, this is the guy for you. I'll be back over and over again, I can't wait to see more one shots pop up.
