Most major, mainstream MMOGs like Lord of the Rings Online, World of Warcarft, and Everquest have complex interfaces organized in a very flat, context-free structure. Movement, combat and non-combat functions are accomplished via the classic mouse and keyboard control combination. Most functions, especially in regard to combat, are accessed via a string of action functions located on "hot bars" or "skill bars". These functions can either be clicked upon directly with the mouse or bound to specific keyboard keys. Although there are occasional exceptions, each key has only one particular function, regardless of the player's situation within the game. Compare the large number of actions located on skill bars to the number of buttons available on a standard PS3 or Xbox 360 controller and you can easily see where basic interface design decisions just don't correlate well between consoles and PCs. It's not that one interface is better than another; they're just inherently different. In attempting to build a game that works on both PCs and consoles you've got to design to the least common denominator. If the console's controller can't support 50 buttons for different actions or can't accommodate quickly selecting actions via a heads-up-display, then you've got to streamline the experience or make it more context sensitive and intuitive. This act of streamlining an interface can only serve to benefit both console and PC gamers in the long haul.
