Same experience here. We spent most of the time engaging either the mechanics or the creative challenges, leaving not enough space nor energy for in character dialogues, thoughts, feelings during heists. Maybe it gets better with practice, but I decided to stop playing BiTD and wait for a more mature version before trying again. It was alright or good for some of the other players at the table. It’s more that I was (mistakenly?) expecting something the game does not deliver then a problem with the game per se.
