Harry Potter and the Half-Blood Prince (PC) vs Prince of Persia: The Forgotten Sands (PC)

Half-Blood Prince features the exploration of Hogwarts and casting spells on objects around the school, similar to its predecessor Order of the Phoenix. The game also includes multiplayer games, classes, different times of day, Quidditch, Wizard Duels and Potion making. The Marauder's Map is included in the game, as further progressing can open parts of the school. Harry can also call Nearly Headless Nick to show him around the school.
As Dumbledore mentions, the Duelling Club begins. Harry is allowed to duel freely with students and learn spells from them. The Gryffindor Duelling Club is located in the Great Hall, while the other houses are in other places such as the Paved Courtyard, Training Ground, and Transfiguration Courtyard.
As Harry attends Potions class, mixing ingredients to make potions is done with the Wii Remote or analogue stick. Harry must also join the Potions Club, which is in the Herbology classroom. Potions ingredients surround the cauldron on the work bench, and through visual symbols which pop up onto the screen you must follow the instructions to complete the potion.

Prince of Persia: The Forgotten Sands is a multi-platform video game developed by Ubisoft which was released on May 18, 2010, in North America and due for release on May 20 in Europe. The game is a latest installment in the Prince of Persia series, and will mark a return to the storyline started by Prince of Persia: The Sands of Time. Prince of Persia: The Forgotten Sands is to "feature many of the fan-favorite elements from the original series as well as new gameplay innovations", according to a press release from Ubisoft. The Prince has the ability to rewind time from the very beginning of the game and throughout the game he learns new powers. The biggest new feature is the addition of elemental powers, which bring a new dimension to the core gameplay, because of the way these powers interact with each other and the Prince's other abilities.
