But I wanted to be able to shoot little sisters indiscriminately.
I get that it's not about pointing a gun at a child, but it would force the player to be careful when fighting a big daddy. Fights would be a lot different if the little sisters could be collateral damage.
Invisible War got away with it, so censorship and rating shouldn't be an issue.
Anyway, lighting them on fire actually should be a valid gameplay choice as someone who thinks like the Templars in Invisible War: not interested in modifying himself, and extremely disdainful of anything that has already been modified.
A little girl surviving a rocket to the face would just be odd, too.
Thanks for posting that bit of insight into the game, though.
