According to this news piece in The Register, U.S. patent 6,769,989 has just been granted to Nintendo. The patent seems to cover all generic aspects of online gaming via a “home video game system”. Update: "Large-scale distributed virtual world technology products maker Forterra Systems (formerly There, Inc.), of Menlo Park, says it raised $14 million in a new round of funding... In another development, Forterra has appointed Robert Gehorsam as chief executive officer." The best way to put the assertion (and this is all it is at this point; and again, please keep in mind that there are a number of familiar exceptions) is that the practice of game software development generates a way of seeing and defining problems (as essentially precise, logical, and algorithmic), and creating solutions (through linear, text-defined code) that makes other ways of accounting for what happens in VWs seem at worst nonsensical and at best irrelevant or quixotic.
