F4LL0UT: To be fair, in games you tend to take on the role of the most highly trained / legendary / super-human dude ever who has more expertise in such actions than anybody else out there - I guess it's absolutely legitimate within the boundaries of the games' conventions / universes.
Still, my two favourite stealth franchises are Hitman and Metal Gear Solid and in both of them evading rather than disposing of enemies is highly encouraged and usually much easier than stealth kills / KOs.
infinityeight: Speaking of takedowns, the Batman games (Arkham Asylum, Arkham City) drive me crazy. I get that Batman is highly trained/legendary, if not super-human, but his flawless takedowns are ridiculous. Batman is famous for his refusal to kill, but that refusal is very unrealistic for a man who gets into violent fights all the time. It makes sense that Batman could approach every fight with the best of intentions: stop bad guy, deliver said bad guy intact to prison. Nevertheless, anyone who lives a violent life, even someone like a superhero who perpetrates violence for good reasons, has to accept that he could very possibly kill someone by accident. Actions that are capable of knocking out a bad guy for several minutes (or even longer) are also capable of killing him. Even someone as well trained as Batman would have to slip up occasionally when he is attempting a takedown and accidentally kill his target baddie.
batman especially the early 1930's and 40's batman never had much of a problem with killing
it was only later that Dc started to tone down his bloodlust
the batman in the movies also seems to have no problem with killing either the burton batman leaves qwuite the trail of bodies behind him
each and every version of batman is different
some kill
some dont
i dont have a problem with a version fo batman killing because it has happend before
but i do agree that a lot of the take down in the arkham series are downright lethal
