Solo RP'ing is an interesting idea, one that I've abandoned a while ago but perhaps should return to.
Anyway, for me, my main character is always a variation on myself. What or whom would I be if I existed in a fantasy world. It sometimes leads to being a little unhealthily close to what I do as my character, but usually it just strenghtens the immersion. You know, being that guy instead of playing being that guy. Perhaps you'll find such approach to your liking. As for alts, well, I can't help you there, since 90% of my alts are short-lived. Unless I have made up a really interesting story for them to follow, I usually drop them sooner or later.

I just discovered tonberrys, and all I got was this stupid avatar... no, wait, it is hilarious!
