selling games. The feature-eroding demo concept gives the user the full game to start off with, but then grows increasingly more limited the more you play it. In racing games, that means the number of tracks you can race on gradually dwindles, whereas in classically themed smack-em-ups like God of War your sword, erm... well, it also dwindles. We're kind of on the fence about this -- on the one hand, it's hilariously insulting to the user as it perpetually nags him about what a cheapskate he is for not purchasing the entire game, and yet on the other it does at least let you taste the full breadth of the game, albeit for a limited time. However you may feel, this is still at the application stage, but given the patent office's recent track record, there's no reason why Sony should be denied the rights over this supposed innovation.
