I have the D20 edition, and while it lets you play a variety of characters from various Federation races it's still a middling product. The D20 stats are goofy for the races, and that was enough to turn me off to the product in general. There are several editing mistakes that made it even worse in my mind. In all honesty, if you want good Star Trek action, I would pick up a copy of Decipher's (?) Star Trek game. It plays similar to D20 in some regards and is and overall better product.
