Business games need development time spent on tuning their economies. Judging by the presence of “Virtual Economy” as one of the features in World Design, that’s a World Design step. Meanwhile, business games in the real world rarely focus much on their graphics. They can be built with downright aging graphical setups without their sales suffering - and a business game which is slowed down by its graphics will suffer a hit in the marketplace. “Minor” graphical slowdowns have extra nuisance factor for players who aren’t paying attention to the graphics in the first place.
This analysis has obvious implications for how the game should handle the Business topic - by reducing the dependence on Graphics and increasing the dependence on World Design.
