I remember Modern Warfare 2 catching a lot of flak for the opening sequence, where an undercover operative is put in a position where you can mow down tons of unarmed civilians (women, children, the whole bit) in an airport.
I also remember a mother recently appearing on TV speaking out against such games as being "disrespectful" towards soldiers and victims involved in current wars, and questioning how we "entertain" ourselves, because it treats situations that have destroyed lives and families as game-able subject matter.
I then remember soldiers commenting on the news article telling the bitch to fuck off, because they liked those games.
Now, I don't find playing a slave fun because that's my preference, but, yeah. Maybe it could move someone else in a positive way, but it doesn't really sit well with me personally. Doesn't mean I should go on a tirade against it.
