I had a PC who was plagued by carrion birds, couldn't stand to be touched - reacting either with panic or homicidal rage when suprised (imagine how well my strangling a child pickpocket went with the group), and was afraid of holy men. With a warped body and overlong limbs, he was a blast to play. Mind you, I added these limits to water down an otherwise powerful character - no feats were gained.
I currently have a borderline personality hexblade (Rook) who is incapable of treating/reading peoples reactions, is coarse, vulger, has a short attention span, and has difficulty in perceiving a world without himself as the center. If he can't get something to work within 1 or 2 tries, he rages (temper tantrum, not the ability), breaks things, yells, shouts, spits, etc. He's great at spinning lies, but runs over peoples feelings and is in general always caught by suprise when he wears out his welcome or his bluff has been found out. Kindness is at a cost and he refuses help if he's afraid a price will be too high - not that a price is asked for (say, a clerical healing). (I love playing this idiot) He's currently saving up his money to buy a monkey paw of wishes. Yep, others say its cursed, but their just stupid - I know how to use it (he's selling magic armor, weapons, and a ring of storing so far, with more money needed!), and will make my money back easy using my 3 wishes. I am, after all, smarter then all of you dummies. (

Doh!)
Also his orgins have him hunted by a hag, a wizard, and a military group (from conception, not gained in game - though I have further hunteds). These result in various screw you events, magic items 'betraying me', my shadow becoming cursed, ..... w/out extra experience. It just fits him.
The hexblade fellow I gave 2 bonus feats for, but as I keep getting in trouble, losing treasure to ill-fated get rich/powerful/look so kool schemes, haggling for what would be given freely, and finding the hardest way to do things, it works out well. I can't wait for him to get the monkey paw and start using his wishes 'smarter then everyone else'.
I don't think the 2 feats overmuch - but then again, I have to admit, as the player, perhaps I'm biased.
