I don't tend to do MMOs regularly, but I found I really enjoyed the social element of playing, something I don't get when playing.. Skyrim or what not.

Though the social aspect can be a great thing or a mediocre thing. I like Guild Wars more for it's mechanics than it's social aspect, since people aren't necessarily sociable.

I miss Glitch. Glitch was fun, but I can't quite bring myself to log back on anymore..
