The recently announced Persona 5 and Persona 4 The Ultimax Suplex Hold. They're yet another reason for me to regret buying a 360 and a reason to make me want to buy a PS3. Makes me sad.
How about some Quantic Dream titles? They make some beautiful games, visually and emotionally. Heavy Rain would be a title I'd love to see across all platforms.
If I had to pick one I'd say Infamous: Second Son. PlayStation has more exclusives and inactive exclusives I'd like to see on Xbox (if it was my primary console) than Xbox having exclusives I'd like to see on PlayStation.
Wait, they're not coming to the 360? I thought they would be.
SMT--which Persona is a part of--is a very Japanese-centric franchise and Xbox doesn't have a strong presence in Japan so it would be a much bigger gamble than putting it on PlayStation and Nintendo consoles. It might have a following of sorts in North America, but Atlus knows that their games have a strong base on Sony consoles/handhelds and Nintendo handhelds.
