Making a game without the game
Everyone knows and appreciates the hard work that goes into delivering a functioning and fun game. You can realize after trying a few games out that some are better designed than others and it has that special something. That special spark that makes it so much more enjoyable than its counterparts. These are fantastic traits to have but they are not the only factors that make a game great. Consider the parts of the game that aren't the development or the artwork. Consider the audience the game is marketed towards and consider the niche it fills in the current environment. To the first question, consider the audience, this asks to whom is the game supposed to attract? What type of people do the designers imagine playing this game? It is overambitious not to mention unreasonable to expect that your game appeals to absolutely everyone. Peoples' tastes and desires range so differently from each other that one game that fits everyone probably just fits nobody instead.
