I wanted the monsters for the 52 Pages to be something unique - not specifically setting-bound; not the same old D&D bunch presented in retro-clone after retro-clone; not just punting the whole issue to the individual DM as in LOTFP.
So I'm presenting more of a monster creation kit. Keeping mind this is my "Basic D&D" for levels 1-3, so I'm leaving out any more than a few high-level monsters. Here's the first page: pretty much condensing and simplifying the approach I take in Varlets & Vermin. And extending it with "templates" ... which are very different from 3rd edition's, much more limited and oriented toward helping create unique and surprising worlds.
