I mean, I liked RotG's battles in that there was only one character... But it was so formulaic, I can't imagine it being fun for a whole game. Half the fun of chapter 11-13 game one was choosing a party with the right paradigms and setting up the paradigm set. That won't be possible with just Light =(.
I've finally learned what torture means/ You sent my first born back to me/ And put a gun in his dead hand/ It's time I take an eye for mine, old friend
