Dantes Inferno was not a hugely well reviewed game - metacritic, at time of writing, puts its average marks somewhere around the 73 mark, depending on platform. It especially came under fire from people who, you know, had actually read Dante's Inferno and felt that EA's handling of it was less than faithful to the subject matter.
Fast forward to March 1st 2012. It was on this day that, for one Dr Elliot McGucken of Los Angeles, the rage that had clearly been building since the game's 2010 release got all too much, and they submitted a US patent outlining the "System and Method for the Heros Journey Mythology Code of Honor Video Game Engine and Heros Journey Code of Honor Spy Games Wherein One Must Fake the Enemy's Ideology En Route to Winning". Now I'm no master in patent reading, but as far as I can tell, the good Doctor is trying to patent various mythological systems of morality and their gaming applications, while throughout making thinly veiled references to how much EA ruined the mythos of Dante's Inferno.
The patent is full of nonsensical gibberish that reads like a gaming madman's handbook. Swinging wildly between heated sarcasm, overuse of the word 'exalted' and attacking string theorists of all things, this patent gives many branching flowcharts explaining each moral choice in a hypothetical game, culminating in the death of Hitler. This patent, and a lot of the Dr's work in general from a swift google, is a great example of just how angry some people can get when source material is messed with.
You can find the patent here.
