like mm i & ii, i will eventually start seeing this as a pretty solid breeding ground of ideas. also, as random stat blocks that i can throw a diffrent description on & use to molest players with. i do sort of wish they could make a book just made of lists of monster powers with like, lots of diffrent artists drawing lots of evocative monster. thats what i essentially use these books for, anyhow. though yeah, i guess once upon a time, a wee tyke m would have found this useful (also, contemplated killing everyone). so i can't fault the way they do it; you've gotta cater to both sides of the fence as best you can.
oh, certain technical things are really nice & geek affirming. level adjustments help clarify CRs, etc. lots more things have ECLs, & they are starting to take the time to explain a little bit as to why the yuan-ti anathema (did someone say jungle cult?), for instance, is such a high fucking ECL. the full attack/attack is broken down to nuts & bolts, as is the AC (into touch, flat footed).
