I had an experience with the Players Option books. And it became clear to me, that if I wanted a game with that kind of added complexity, I would still be playing Rolemaster.
The Skills and Powers book to me utterly ruined AD&D 2nd Edition. Turned it into an inaccessible mess I just didn't want to play anymore.
Every book that Wizards puts out under the Players Option banner makes me simply not want to buy it. Because of the wretched legacy of that line.
