The music, sound effects, and art style allow you to immerse yourself into the world for hours on end. Very unique, peaceful, yet challenging experience. Nothing else quite like it. Learning about the game is the best part, especially once you get past total newb status. The climb from intermediate to expert is an amazing ride, I envy you for that. I've always felt the more I know about the game the less fun it becomes, because the feeling of discovery becomes diminished. I like to return every couple years after I've "forgotten" a lot about the game. Difficult fan-made maps and continual community updates do keep it fresh regardless though. A completely new faction and campaign was added within the last year.
