In the interest of demonstrating that the topics I ramble on are not completely isolated insanity, here's a link to an article on Terra Nova that expressely deals with the topic of ilinx in MOGs. Here's a quote:
I associated ilinx with more physical activities (like *real* base jumping). But after thinking about it a bit, I suppose there's a long history of ilinx in video games. Jess's description of the bridge stunts in Air Warrior were, at least in part, about the thrill of sheer speed. And the rush of movement is certainly the most prominent feature in the popular genre of racing games, from Pole Position to Crazy Taxi.
My thoughts on ilinx in videogames, for those who have not seen them, can be found in this post.
