I think Divinity II: Ego Draconis is a very good title for a rpg.
A bit of latin is always classy and it's also somewhat mysterious: Chances are folks won't exactly know what it means but that it has something to do with "dragons" and "yourself" and will be intrigued by it (that's how it was for me until I read the thread's opening post

).
Plus, I simply like the sound of it. Kinda cool.
