How dare you make ads for SONY
But anyway I like being the evil Casa-Nova like blade. Charming intelligent dangerous and convincing - you know your local demi-god off the block!
I like it because from a role-playing facade I play with some good party members (minsc mebe anomen Aerie) who are to gullible to see through my facade to understand that they are just my pawns.
It also (still from a roleplaying point of view) allows me to do the 'good' quests so that My rep goes UP prices come DOWN and I can better betray the populace afterwood...
