Great Scott, my dimensional transport works! I've found a world where Nintendo and Sony's place in video games is the complete opposite of my own Earth!
Looking at the making of "God of war", I can see that they must have went through a lot of design ideas before we got the game we all know and love. The play tests actually helped.
Play tests are what makes or breaks a game. At least now you know if the game can actually be cool for every type of player.
