I'm sorry, I cannot adequately answer your question. Your definition of fun and mine may not be the same, and suggestions other people have made have been summarily met with rejection, dismissal, and a statement that equated to them being mistaken for considering the other parts of game you have not sampled yet to be fun.

What is being said to you, is that there is a large part of the content, both in the mechanical and the social aspects, that it seems you have not tried. It is recommended that you take the effort not to pigeon-hole your experiences in the game, but broaden them. There is a lot that you simply have not done, have not tried and may consider fun if you do actually try them.
