5. You know who wants to hurt you
Game designers put a ton of effort into making sure you know, and can immediately recognize, who the bad guys are. They’re big scary monsters shambling at you in the dark. They’re hungry wolves leaping out of the forest. They’re terrorists or mercenaries hired to topple your government. They’re on the Red Team, the bitterest of your Blue Team’s rivals. Whoever "they" are, they’re nothing like you--in fact, they’re sworn to bring down all the good, noble things you stand for.
In reality, the people out to get you are never so obvious about it, are they? Sure, there’s the guy who mugs you occasionally, but more often than not, the people out to do you harm are the people you’ve known and trusted for years. Your bank manager pressured you to borrow heavily to buy a house you couldn’t really afford. That old gossip three cubicles down has been telling your boss how lazy you are behind your back. Your mom keeps trying to scare off your significant other whenever they’re alone together. Why? Who knows? Some people do it for profit, others just like to watch you squirm. Makes you wish all the bad people were easier to spot and avoid, doesn’t it?
