I bought a full retail priced demo on my 3DS.
I'm not angry at all though. I was always gonna get both. As we draw closer to the WiiU release I haven't been hoping "wow I hope there's nothing new and interesting to differentiate the WiiU version."
On the contrary.
I was praying for subspace emissary 2. Longing to some crazy fanservice mash em up cutscenes, deep down in my heart.
