No it doesn’t! For any completely obvious observation you might make, you can also find someone who has obviously forgotten or failed to observe it, and you can probably find someone who sincerely disagrees with it. You can find someone who has failed to observe it at high stakes, like millions of dollars or at the risk of his/her life. People mess up the obvious all the time.
This observation probably also seems obvious to you. You know that people make obvious mistakes all the time. And yet you are still surprised by it sometimes. You can be oblivious to the obviousness of obviousness.
The Declaration of Independence holds these truths to be self-evident and then goes on to spell them out. It seemed kind of important to make them explicit. Also, you can name more than a dozen countries where you can still be killed for saying all of them in public.
So Ravious’s title is quite apt, and even if the principles seem patronizingly obvious, how long will it take you to name a dozen games that violate them? How many seconds will it take you to name a company that spent nine-digit sums developing a single-player MMO? You’ve seen me post about the obvious or trivial or review years-old games. Beyond the (obvious) fact that there are always new people to whom old insights are new, we forget old insights or forget to apply them because they seem so obvious. There are new implications to be found in old data. There are unknown knowns.
