Of course, Fang Zheng wouldn't know Asuna's thoughts. After returning to his room, he opened the inventory and took out all the miscellaneous items like needles and threads he bought while shopping, examining each one.
As Fang Zheng and Asuna had discussed earlier, every game has its priorities. Take NPCs, for instance. The protagonist is always the most detailed, followed by the heroine, and then other supporting roles. As for those NPCs or shopkeepers running around the streets, they are usually created using a template, with a random hairstyle and skin color put on.
The same goes for weapons and equipment. The gear you buy on the street obviously can't have cool particle light and shadow effects; otherwise, who would fight bosses for gear? Generally speaking, the more important something is in most games, the more detailed it is, and the less important things are naturally simpler.
