Good question...
Robots are creepy in a sterile, AI, terminator-esque quality. I think they appeal to the man vs. machine (our own creations) mythos. Generally, they are almost unstoppable and either emotionless or psychotic. All fantastic points in my book.....
but
Monsters can really run the gamut from mutated person (corrupted versions of ourselves) to hideous creature of unknown or ancient origin. I feel the door is kicked open a little wider for the monster set, because of this. Tragic accidents, broken hearts, pure evil, etc. can manifest itself in countless forms, rituals, and stories. I've always liked the historical instead of futuristic vibe: stuff like the Elder Gods, Kraken, Wendigo, aliens, vampires, bigfoot, nessie, etc. I think that belief is more easily suspended when we have inspiration like current or extinct species, genetic engineering, medical sciences, not to mention the realm of ethereal, "unseen" forces.
So, until hms commissions a custom from me....
make mine monster!
That being said, I had to place my vote for Robots- And its not even the unstoppable killing machine variety, I like my robots with charm and character:
As someone already said tho Monsters do open up allot of possibilities imagination wise. I like em 50's 60's campy tho both coming from movies and old EC comics.
