I want to be a good player in every class, make every mag(including all non-rare evolutions), get every item, essentially, going for 100% completion. This is what I aim for in most games I play, and will probably never be achieved in this game. I've put in over ten years trying to do it in other games. This is a very complex game so I find it is often becoming new to me again when I experiment and play around. Which is why I really enjoy playing the different classes, the different section ids, and seeing what is possible with mags.
The reason I chose to get into this was because there is a great community here, however if I didn't like the game as well then it wouldn't be enough to keep me, online communities come and go. It is sad because you make friends with people and then one day they are gone but it is also just the nature of this sort of thing. We all have real lives outside of this that are more important, even if you are like me and pretty much ignore it.
