Sony has confirmed that only human avatars will be available in PlayStation Home, making it impossible for you to set up shop as any number of weird non-human entities.
Officials also said that the number of costumes available will be limited, in order to keep things as normal as possible. That means the even though they're "human," you won't be allowed to parade around as Sailor Moon or a Stormtrooper.
It's an attempt, on Sony's part, to make freak and non-freak alike, feel welcome when visiting the Home realm. Executive producer Peter Edwards explains:
"If everyone's walking around dressed as Orcs or Stormtroopers or whatever, then you lose that welcoming, accessible element that means Mum, Dad and your sister might get involved as well," he said. "The idea is to keep it as accessible, mainstream and friendly as possible."
Snaps to Sony for knowing their audience! Although, we're putting money on the fact that this announcement, which comes as a big slap in the face to Sony's core following (basically by calling them weirdoes), will fuel a number of hacks which will flood Home with a bajilion Orcs and other odd mythical creatures. And penises.
