Nobody knows who is the hero of Killzone. Replace him with a charismatic, well known character. Since Sony's biggest franchise is Gran Turismo, a Nissan GTR would be the best choice.

Sex minigame. It works for God of War, so why not. Kratos could do a cameo in it, and maybe Kaz Hirai.

Boobs. I don't see how this could be a bad idea. They seem to be quite popular here too.

Love story, sad end. This should guarantee 90+ reviews, even if the framerate is awful. Just look at SotC.

Only for Japan, region lock. This will make the game massively popular in gaming forums.

I would buy 72 copies of this game, even though I don't have a PS4.
