Rumor going around that Michael Jackson: The Experience Demo is actually the full retail game. People are downloading it and it doesn't ask for an unlock and has all songs and trophy support. Did Sony goof?
I just went on and downloaded it. The Demo is the same size as the full game and the icon doesnt days its a Vita demo
I don't have that much money right now so i will only be starting out with uncharted and dynasty warriors the first week but a 32gb memory card
