From the introduction:
For years, Tactical Studies Rules (TSR) has being trying to placate gamers desire for diversity by releasing more and more monsters for the AD&D game. The problem is that there are only so many monsters possible before the designers find themselves really scraping the bottom of the barrel. Tactical Studies Rules (TSR) has been there before, the flumph really was lame and I’m certain that the beholder was designed when Gary Gygax had a serious case of writers block and came up with the utterly pathetic idea of “a big eye with lots of little eyes that eats characters for breakfast.” But somehow Tactical Studies Rules (TSR) has managed to bounce back. The beholder turned out to be really quite good and the flumph was only a minor hiccup. But now I say enough! There are no more monsters possible! Monsters are becoming increasingly lame and pathetic. Let this netbook serve as a warning to all those who’ll buy anything just because it has the Tactical Studies Rules (TSR) logo on it. It might not actually be any good. In fact, the creatures in the next MC - Monstrous Compendium appendix might just end up like the ones here. Although that would truly be lame.
