To be perfectly clear, there are lots of potential reasons to decide that you no longer wish to play a particular MMORPG. It’s not that anger or boredom are the only potential reasons. Rather, it’s that those are the two most obvious reasons to move on. Either something happened to get you so miffed that you decided you were just done with this game and you storm out, or you’ve just accomplished more or less everything that you want to do and so you wave goodbye.
Neither of these are necessarily permanent; it’s possible for you to leave a game out of anger and come back multiple times, just like it’s possible to be bored and then decide you want to accomplish something new before returning. Nor is either one a law of nature; maybe there are games you’ve left in anger and others you left in boredom, or maybe it’s even the same game. But the question today is which one is more frequent. Are you more likely to leave MMORPGs out of anger or boredom?
