Every stories are simulations. Every media use mecanics and rules to simulate his story but TB games completely transform the first of all real things : time. TB leads you from a totally realistic system to another reality in which time management, movements, actions and reactions,...everything become different and totally unrealistic.
Realistic films and books would be boring. Realistic games would be boring. It all comes down to what makes want to bring out.
Edit. Abstraction isn’t a problem if it’s consistent. It might not be to your liking and it’s fine. Theatre asks for a lot of suspension of disbelief, but it doesn’t make it inferior to films. TB might ask for more suspension of disbelief but gains and fleshes out other aspects.
