Gof’nn Hupadgh

Also known as Satyrs or the Blessed of Shub-Niggurath, the Gof’nn Hupadgh are a mutant race, some having the semblance of satyrs with goatish features, hoofed feet and small horns, others being mostly humanoid, and still others having been horribly mutated into monstrous things. They were originally humans who were sacrificed to Shub-Niggurath, and are "reborn" with great mutations. No two are alike, and it's said that they served the basis for ancient goblin myths.

In the RPG...

The Gof’nn Hupadgh have roughly human-ranged stats, though CON and DEX are at the upper level. The 7e Malleus Monstrorum has added a "Greater Satyr" variety as well, whose stats are higher again, though the averages still (just) fit within the range of a human. Fighting types and abilities are left vague because Gof’nn Hupadgh come in different animal forms, so each would have its own (such as a goat or bovine mutate having horns). 

    The Malleus Monstrorum points out that Gof’nn Hupadgh know a type of gate spell called the Scarlet Circle. Unlike a regular Gate spell, it is created via a blood sacrifice, and there is no mention of POW or SAN loss to use it, or even limitations on distance.

In a video game...

Being humanoid and killable, they would work fine in a video game, however, the fact that "no two are alike" and "are generally encountered in groups—sometimes very large groups", it would be a lot of work for—what I feel—is very little payoff. Perhaps if only one or two were encountered they would be worth it. Especially if the player was there to witness their "birth". The Malleus Monstrorum doesn't specify a SAN loss for such a sight, but I imagine it would be suitably horrific.

In a film...

I have a feeling that a group of ill-formed and goat-traited humans might look a little goofy on the big-screen. I'm thinking of The Island of Dr Moreau here. Who knows, it could be done well, but I'm just not seeing it.
