I was actually pretty impressed with this PDF, as it really gave me a solid idea of how to incorporate awakened primates into both my d20 Fantasy campaign and a number of different d20 Modern settings (Psi-Watch and cyberpunk, to give a couple). I also enjoyed the photography, which really fit the theme of the document. However, "Free 20: Monkey Business" could have benefitted from the following changes:
More careful editing for grammatical errors (i.e., page 2 underneath the Spot Check Dc heading, where it discusses how some "uplifted" (rather than "awakened") apes might be covered in arcane "rules" (rather than "runes") based on origin.
- More thoroughly detailed differentiation between the different breeds of primates (e.g., orangutans, gorillas, bonobos. gibbons, baboons, mandrills, lemurs, spider monkeys, howler monkeys, etc.). As such, this PDF only goes inbto describing large apes (gorillas) and small apes (chimpanzees) and doesn't really talk about actual monkeys at all, which contradicts the title "MONKEY Business" to a degree.
*Racial classes for each breed of primate with appropriate Talent Trees for each breed a la Peter M. Ball's "After Sunrise" series for vampires and werewolves.
Other than that, you really can't go wrong with this title, especially considering that it's free to download. I say give it a shot.
