When I saw the use of shit, I was perfectly immersed. However, for whatever reason, the word fuckers broke me. *shrug* I think in all my experience, f-bombs were always replaced with something else. And even if it became kraft level of cheese, it added some levity to the setting. Which, also breaks immersion.

Rock and a hard place with this to me. If it breaks my immersion, it isn't long before something in the game sucks me back in. So it is not too high on the priority list for make or break to me.
