One of those games can be a moving simulation. Like Yukon Trail. You get to pack Kratos' bags and move to rome!

I wander what Santa Monica will make, once they are done with GoW...
Another action game?
An RPG?
A small PSN puzzler?

I think it would actually be a good thing if they make a puzzle game, they have proven already that they make some epic puzzles, and it would break up the pace a bit. Then they could do something else afterwards.

I always knew that

Kratos will be missed.

it'll be the last coz kratos will destroy everything. if everything's gone, there can be no more games.

anyway if the game sells well the option of making GOW 4 is still there

 The titles of thos games would be "Kratos Moves to Rome" and the synopsis would be "After the mythical greek god took his revenge he became lonely. He grew depressed and set of to find companionship. While on his journey he was passing through Rome. That's when it all started to happen..."

Or no one to play the games?

He wont destroy everything, he is going to make everyone atheists

Yes. Zeus turns out to be alive, powered by nanomachines.

the next one could be "The Titan of War" and Kratos can kill all the titans!
