I wouldn't mind being a Ghoul, but I can understand why you can't have a "Super Mutant" character - 99% of NPCs would attack you on sight, you'd need an entirely separate origin story (unlikely that a Super Mutant would be in a Vault filled with humans), and you'd have to redesign all the clothes to fit the super-mutant's bulky frame.
But playing as a Ghoul would be awesome - specifically a ghoul that has survived the great war until now. You could still start out in a Vault - just make it so that your character got a dose of radiation before they could get to safety of a vault.
Being a robot would be too difficult, storyline wise - unless you're talking about an android a la Blade Runner, which would be an undeniably cool choice.
But I can understand why they've stuck with human main characters - the others would be difficult to implement.
