Advantages and disadvantages

["jcorey30" <jcorey30@yahoo.com>]

DragonQuest is my game of choice.  But that is not to say I have not 
been tempted to stray.  and I would play multiple games if I had the 
time.  One of the games that intrigues me the most is GURPS.  and I 
will tell you why...
It has a built in "role-playing" system.  When you create your 
character, you have can give them advantages, disadvantages, quirks, 
and habits.  This helps to define someone's character.  and they 
force players to behave in a certain 
fashoin consistantly.  Now, I have never played GURPS (but i did play 
Fantasy Trip), so I don't know how this works in practice.
So I am asking two questions...
1) what do you think of these kind of reward/penalty systems?
2) has anyone tried to add one to a DQ campaign.
