My #47 (as guessed by axumblade) is Prince of Persia: The Two Thrones. For me, it's the best of the Sands of Time trilogy -- one of the greatest video game trilogies ever made. The game borrows elements from both its predecessors, and adds a few new mechanics. You get the acrobatics and puzzle-solving that define the series, plus new stealth fighting techniques and chariot stages. And a great story to boot.
