There's lots of other speculation about why PC gaming is on the way out. Shamus Young (http://shamusyoung.com/twentysidedtale/) generally has the view that PC gaming was killed by a) Excessive focus on graphics (which he has termed "bling mapping"), and b) Overly byzantine DRM. But mainly a, although the response to spore seems to indicate that people gasp actually like owning the things they buy.
