It's probably cause it's a very subjective opinion.
I on the other hand, being a completely objective person myself(unnecessary I know, i'm just testing your grammar), am gonna give a rational and logical conclusion to your query.
Nothing much other than the fact that is it fun to play. Good music, art work, mechanic, that's all there too, but I just need to have fun.
This isn't tp say I have my preferences. I like RPG and Strategy and even some good music.
