Games are not art. They are trying to sell themselves. So developers should try to sell the games as best they can. Mostely that entails making the games fun. Therefore, developers should try to make they're games as fun as possible.
"Pier was a chef, a gifted and respected chef who made millions selling his dishes to the residents of New York City and Boston, he even had a famous jingle playing in those cities that everyone knew by heart. He also had a restaurant in Los Angeles, but not expecting LA to have such a massive population he only used his name on that restaurant and left it to his least capable and cheapest chefs. While his New York restaurant sold kobe beef for $100 and his Boston restaurant sold lobster for $50, his LA restaurant sold cheap hotdogs for $30. Initially these hot dogs sold fairly well because residents of los angeles were starving for good food and hoped that the famous name would denote a high quality, but most were disappointed with what they ate. Seeing the success of his cheap hot dogs in LA, Pier thought "why bother giving Los Angeles quality meats when I can oversell them on cheap hotdogs forever, and since I don't care about the product anyways, why bother advertising them? So Pier continued to only sell cheap hotdogs in LA and was surprised to see that they no longer sold. Pier's conclusion? Residents of Los Angeles don't like food."
