Save it for PS4
Bit of a controversial one this. God of War has always been about huge scale and spectacle, so imagine what Sony Santa Monica could do if given the increased power of the fourth PlayStation.
The opening half an hour of God of War 3 was one of the best sections of the game. Giant Titans scaled mountains while fending off Gods as Kratos scaled Mount Olympus and fought Poseidon. Set pieces like this have defined the PlayStation 3 and we'd happily accept if Sony left God of War 3 as the only game in the series that appears on the current generation.
Imagine if God of War 4 was a launch title for the PS4, complete with an even grander scale, increased draw distances, and even more jaw-droppingly huge enemies. It would be stunning, and the perfect opening act for the PS4.
Considering that this generation we've seen not just God of War 3, but also two PSP titles in Chains of Olympus and Ghost of Sparta and the God of War HD Collection, we think that fans have certainly got their fill of Kratos for the time being and would be happy to wait until the next generation for a new entry in the series.
