One Piece: Pirate Warriors is based on the popular (we'll give them the benefit of a doubt here) anime series. Players jump into the role of Luffy and other pirates then team up with other members from the Straw Hat crew to defeat wave after wave of enemies in both online and offline co-op modes.The game commemorates the 15th anniversary of the One Piece manga and anime franchise by Eiichiro Oda. One Piece: Pirate Warriors releases exclusively on the PlayStation Network on September 25.

Thundercats fan we can associate with a little more. Fans of this revolutionary and entirely flawless animated series should mark their calendars for September 25. This new Nintendo DS game follows the plot of the new animated series and sees Lion-O battling Mumm-Ra and his forces of evil in a side scrolling adventure.
