But the minute you add rapping and torture, it seems you might just be crossing the line.
Personally, I wold love to see a roguelike with rapping. Demoralize your opponents and gather followers with tight rhymes and wicked flow.
Killing in games doesn't offend anyone because it's so present in everyday media. People don't pay attention to it as long as it's not happening in their immediate surrounding. Rape, on the other hand is much more dodgy, you rarely see it in the movies. Myself I would feel really uncomfortable to see it in a game, especially if I was to do it as a character. Similarly, I wouldn't put it in my own game. It's not that I think rape is any worse than murder, it's something else, maybe in the culture.
Really, a large part of that is because rape hits a lot closer to home for more people. There aren't any murder victims playing games (by definition), but there are a
lot of victims of rape and sexual assault (I think the statistics are 1 in 3 women and 1 in 6 men? Which is part of the reason women react more negatively to it, Endorya...it's something that is very likely to happen either to them or someone they're close to, they're not really being unreasonable, don't discount what they're saying just because you disagree with it). Since it's such a traumatic experience, a lot of people have some amount of PTSD about it, so experiencing realistic depictions of it can cause some pretty bad reactions (not just feeling uncomfortable, but panic attacks or flashbacks). On the flip side, treating it too lightly when it's something really really bad that happened to them is probably going to cause people to feel kind of uncomfortable about it at best, offended at worst (and partially that's cultural, rape is not really taken as seriously as it should be by most people considering how prevalent and traumatizing it is).
Now, of course, on the flip side there
are people who have been victims of nonsexual violence, who might have PTSD and who might be made uncomfortable by depictions of violence. The difference would be that the types of violence they've experienced are probably not very like the types in games, and there's also a lot of ways to show violence without it being gratuitous or realistic, so that it might not bother even people who have been through it. Also, if they feel that way, they probably
know how violent a game is going to be before they get too into it, and the violence is probably going to be an integral part of the game, so it's easy for them to know if they're even interested in it or not. If there's a rape, someone could have no problems with the rest of the game, but that one part could be so upsetting that they stop playing, and for what? What does rape add to the game?
And that's really the question you have to ask yourself:
Why do you want to portray rape in a game? What purpose would it serve? Are you trying to make a larger point? If it's just to be "realistic," because, you know, someone
could rape someone else, I don't really think that's a good reason. Are you going to include pissing and shitting too?
Is it just because nobody else is doing it? That's not necessarily a reason either. There are reasons nobody else is doing it. Now, I don't think that it's impossible that a game could handle rape well, but I find it pretty unlikely that putting it as an optional feature in a roguelike is going to be handling it well.
With regards to torture, there are some games out there that do feature it, but I think that's really just a "good guys don't use torture" thing. Dungeon Keeper, where you explicitly did play as the bad guy, featured torture chambers, and in Liberal Crime Squad you can kidnap and torture people (mainly psychologically) to brainwash them. Those are the only ones I can think of off the top of my head.
I think torture would be something that would be a little more socially acceptable than rape, especially in a medieval fantasy setting. In a modern day setting where you have to waterboard or electrically shock someone? That'd be a little dodgier, and again I think you'd really have to think about what you're trying to say and why because, again, it's something that's still going on so it hits a little too close to home.
