800 new monsters, you say? How many of those are the same guy with a slightly different name and color pallete, plus or minus a few hit points or abilities? Heck, how many of those are new models, rather than declaring this green-ish orc the “orc mauler”? Would 40 be a fair guess? It feels optimistic; the 158 types of undead must have at least 10 models amongst them, but I don’t know that the 321 types of orcs have 20.
This from the game that advertised how many characters had been made.
