The Pub RP's a good place to start or try out a character, you can make and bring any character imaginable into it to talk and interact with the other patrons (players), and you can enter and leave when-ever you want. In my time there I've encountered among other things talking animals, robots, zombie survivors, dwarfs, elves, small kids, super-heroes, aliens, characters from video games, all kinds of magic users, even the occasional normal person ;-)
