I don't know how in the hell Sweet Tooth can look any scarier than he already does, so a Halloween costume is out.
It doesn't always have to be scary. They could replace his normal mask with a hockey mask.
I guess but do u really want it to be like a shooter with so much dlc it wouldn't all be free.
If its for free costumes that only happen once a year, like how LittleBigPlanet does things, I'd totally be up for it.
And yeah, IP holders would be iffy. I'm hoping it happens but nonetheless aware its likely never ever going to.
