Today we are going to play pretend. We will pretend to be in the process of developing a game with the goal of being worth a particular price tag. Since we are ambitious, we want to be just like the AAAs and charge a hefty $60 for our game. But we are also familiar with the hours-to-dollars assessment people use to judge if the game provided enough entertainment to be worth the pricetag. If we use the price of a new DVD as a measuring stick we can guess that our players will want their entertainment on a 10:1 ratio ($20 = 2 hours of entertainment), so for our $60 price we’ll need to provide six hours of game time. That can be a lofty task for a single player game, so today’s article will be delving into the wonderful world of design mechanics/strategies to extend game time (for better or for worse).
