Prince of Persia was, also, a good game. However, it had a good natured hero trying undo his wrongs.
It did not sell so well.
Prince of Persia: Warrior Within takes the first game and makes the hero a killer maniac who cares only of himself.
It sells double of what the first did.
Nope, can't be the change of tone. Not at all. No chance.
