I grabbed the Player Companion after my first game with QUERP and was not disappointed. The rules for custom characters look to be fun and once my children (12 & 15) are better aquainted with the game I will use those rules.
That said the selection of character types (14 classes) is huge and gives a wide variety of choices. My son is changing his warrior to a Knight as I type.
The selection of non-human races (9) and how they work is well done and provides enough that you can cover most of the races you might want.
This is rounded out with new equipment and new spells. On the whole an excllent buy and well worth the money.
