Kojima games have always been full of mechanics and characters that are pretty obviously direct jabs at his own player base.

Hrm, after MGS, what does my NA playerbase look like?

Oh, a bunch of skinny, white, emo nerds with massive insecurity about basically everything in their lives?

Perfect, that’s the new main character, and he gets a shonen character arc.

… MGS4 legitimately got me to get a portable cigarette butt container, and then also helped me to quit smoking.

You can also trigger a fairly bizarre cutscene where your character takes a shower with one of the female characters but she keeps all her clothes on, if you cultivate a certain level of unrepentant stink.

I love MGS5

Nonlethal is just as easy as lethal. There’s a morality system that goes with it.

If you kill too many people and don’t wash off their blood then you become permanently soaked in blood, and Snake grows a little devil horn. No matter how many showers you take you will never wash away the blood.

You ever skip taking a shower for a day or two just so that the next shower you take feels even better?

Hideo Kojima has a secret message for fans.
