         <text:p text:style-name="HeadB">Rationale</text:p>
         <text:p text:style-name="Note">Readers with some experience writing games may be balking at this point, thinking that a MVC architecture is too abstract, and that it will add unneeded overhead, especially those whose goal is to create a simple, arcade-style game.</text:p>
         <text:p text:style-name="Note">
            <text:soft-page-break/>
         </text:p>
         <text:p text:style-name="Note">Now, historically, arcade games were just that, games written for arcade machines. The code ran "close to the metal", and would squeeze all the resources of the machine just to get a 3-color ghost to flash blue every other frame. In the 21st century, we have resource-rich personal computers (and phones!) where applications run a couple layers above the metal. Hence, organizing your code into a pattern has a small relative cost. For that small cost, you get the following advantages: more easily add networking, easily add new views (file loggers, radars, HUDs, multiple zoom levels, ...), keep the Model code "cleaner" by decoupling it from the view and the controller, and I contend, more readable code.</text:p>
