it seems the professor's works don't contain much heart-fluttering romance nor scandalous affairs, it's either happily ever after or tragic. not that it's bad but somehow it strengthens the setting of a civilization with a rather straightforward morality. the only "twisted" characters are the enemies.
in relation to RPing, I haven't tried it, but it would seem difficult to be in character especially if you're an elf. age matters obviously, you can't claim to be born in the middle of the 2nd age and was just eating lembas during the war of the last alliance or fall in love without consequence with a man. I'd very much rather be a hobbit with less lore to support my behavior
