I can 100% agree with this, and not because I can't handle Violence or Mature themes, but because I generally prefer to play games without blood. I've made exceptions, but all in all I prefer my screen to be a bit less cluttered when I shoot someone, regardless of realism.
Edit: I would like to say I'm not asking for a cleaned up version of any Rockstar Games and do not hate Rockstar, but I would like to option to toggle blood, and maybe language as their games can get quite foul, and nudity as I feel it is unnecessary, on or off. It wouldn't actually be that hard ehen you think about it, since its only removing thing. But I think that RDR2 will probably be a hit, and as a fan of American western, I might even consider it.
