Suppose there is a game with two kinds of enemies, the ones who appear most of the time and are easy to beat, always in packs with similar behavior and give a very very small reward, *and* the rare hard ones which should be avoided to stay alive, but their defeat means great rewards(each one of these being worth more than 1 million times than the first kind), each one of these with different behavior and abilities. Suppose allies exist, and look different from common enemies, and giving 10 times the rewards of the common enemies without the risk. Suppose that none of these has to be found, instead they find you. Suppose that the hard enemies can look like the first kind of enemies or like your allies, and only when they attack you can see the difference between an ally or a common enemy and a hard one. How it feels not knowing when an ally isn't one really? which kind of enemy would you like to fight more? would you be afraid of the hard enemies? What would you do if both kinds of enemies are together at the same time? How do you think other players will react?
