What are the impediments to designing the ultimate game?

[Espon]

The problem is difference of opinions. People want different things from a game, so you cannot satisfy everyone without extremely bloating the game. And not just players, but the developers as well.

A company also has a limited number resources; be it money, people, or simply time. You can only throw so much money and people at a game before it all starts to bottleneck. You want the game to be a quality product and not riddled with bugs and other issues. The more that gets added at once, the more testing is required.
