Short Version
This is a good update to D20 modern. It's far less restrictive when it comes to class features, witch is a good and bad thing at the same time. While it makes your character completely customizable That can lead to two things, ineffective characters and super powered ones. Being only $5 makes it well worth the investment. It's a good idea but I wish it was more developed.
