You can't evaluate the third installment based on the standards that applied to the fifth. Of course, you can criticize the graphics in the third game, but it couldn't have been different at the time. Is it normal to take all the best elements from previous installments, practically invent nothing new, and add modern graphical capabilities? This isn't the kind of series where you should do that. And you need to maintain the image of the company that took on something almost sacred. Otherwise, you add a unit, remove a unit, redraw a unit, add a building, change the number of resources, and then tweak the graphics a bit – and that's it?
