Well, for me, the idea of getting into another character, with his/her own set of ideals, dreams, motivations was really endearing. Well, it's pretty fun overall. I got into role playing after accidentally getting on some roleplay server on Runescape, asked one of my online friend what it means and everything else is history, sounds cliche, but hey that's how I got into roleplaying.

Also I guess its a good way to forget that the world is really boring, even for just a moment.
