Because consoles don't have keyboards, console games are extremely limited in the kinds of social interaction that they can support, which means that console-based games tend to be focused around kicking, jumping, hitting, running, and other brute force physical activities. This in turn limits the console market to a fairly narrow demographic, one that isn't interested in complex social interaction. Similarly, because consoles don't have hard drives, they are limited to games which are mostly "stateless", meaning that the player can only affect a small number of selected variables in the game environment.
