Now this is not a brand new concept by any means. In fact this concept has been used in many best sellers. And not to overkill the entire Fallout 3 idea, but this concept was very well done in the latest Fallout installment. And in a more close to home example, we can all recall The Legend of Zelda: Adventure of Link. Though a very primitive game compared to the massive games of today, The Adventure of Link was the first Zelda game to introduce the concept of skill leveling. However, since its release Nintendo has veered away from this concept and generally has avoided the entire concept of skills.
