The imperium is a big and diverse place. I would like to hear what kind of cultural twists you come up with that really spice up the game.
Last game session my players was on the outskirt hive planet Vaxanide, and I decided to spice up the game they would have cultural twist akin to Indias holy cows. There was a deep rooted belife on the planet that the Emperor was protected by his lojal cats. because of this you found cats all over the hive since all homes, resturants, hotels, monorail stations and stores tended to have cats of thier own to ward off evil. And all cats were genreally very spoiled and cuddly.
Some how all of this took spin. The dusk moriat assasin freaked out convinced that the creatures were dangerous (and that by Dusk standards), since they vere protecting the empreror and all, and went to great lenght to not anger these cretures.And the tech priest turned crazy cat lady, cuddling and carrying around cats most of the times and explained every failed roll that session by cuddling, proteting and being distracted by cats. And the whole group started solving problems by taping the id tags to cats (cats+tape gives interesting results. Youtube it) etc
The whole session was really spiced up by cats and the players really got feeling of the ever present presens of cats in their descrotions, plans and actions.
What sort of weird cultural twist have affected and colored your games?
