How would you all feel about getting spirit-boards without getting characters?
Do you think you'd personally enjoy that more or less than Mii-Costumes?
It depends on the characters. I'd hate if Amaterasu was reduced to a grotesque Mii hat, but I could see her Spirit battle being really fun or unique.
I keep going back to the Resident Evil Spirit event. I thought it was really clever and well done. I'd love to see a TWEWY Spirit event for that reason, especially since SE doesn't seem to be releasing any more Mii costumes.
I'd rather have the costumes, but some characters would just work better/feel better represented via Spirits.
By the way, I think a LOT of the most talked about heavy-hitters are going to be costumes or passed over altogether. If Master Chief, Doomguy, Hayabusa, Reimu, or the Knight are going to get any representation in Ultimate, it'll be via costumes.
I have nothing to back that up, but it's what my gut's telling me.
