This is what Morrowind does. It\'s not bad as an extra feature for the customization of your character.
It\'s fun stuff as long as the property is useful. The thing about Morrowind was that a select few of those signs were very useful, but the others did more harm than good or did too little.
What\'s nice about the star signs was that they helped enhance the type of character you want to specialize in. You can decide if you want to steal, talk to animals, be on friendly terms with npc, want to have more mana, and so on...
