Prince of Persia is a strategy game? Since when?

I think your englishness is fogging your brain.

Halo Wars is going to be a Real Time Strategy game. Prince of Persia is in no way a Real Time Strategy game. Real Time Strategy game=Red Alert, Command and Conquer, Starcraft, Dune whatever, Age of Empires, Age of Mythology, Rise of Nations, Warcraft, etc.

EDIT: Assassins Creed is considered an Action/Adventure game, while Prince of Persia is considered a platform game. Neither of those are Real Time Strategy games.
