Why Sony can't just let God Of War die and move on?

[JustThatGamer]

There's nothing worse than entitled gamers exclaiming that certain franchises should die, get over yourselves, if there's millions of fans begging for more and the quality stays consistently good then what's the problem? Look elsewhere for new IP.

God of War's universe is so open, it could continue in so many directions. I hope they introduce Egyptian mythology if only because of this amazing fan art...
