Name the points that makes your game fun, how it should look and why.

This is my question to community, since I seen countless people talking about game like its work, when its suppose to be fun pass time. At this day and age game is one of the major community forming power, but most of the time its stressful and more like work creating just one more working enviroment. Help me a member of this community see once more why are the online games fun and how should I play them to be it so ( No clan, parties or friends purely game form) and as you answer this question you will once more have fun playing, as you will answer this question for me and yourself.
