For one day only Amazon is offering Pokemon Black and White, the most recent games in the core Pokemon series, for $25. These Nintendo DS games feature over 150 new pokemon and an entirely new region. Pokemon veterans will be happy to hear that TM's now have infinite uses, and experience gains have been scaled to make levelling low level Pokemon easier.

This entry into the Prince of Persia series is set between the Sands of Time and Warrior Within, and features time travel based gameplay and action sequences.

This is for the PS3 version only. Lords of Shadow features beautiful graphics, great voice work, and intense action that pulls inspiration from God of War and Shadow of the Colossus.

Another good discount in the Gamestop power saver sale, Borderlands GOTY (which includes the first 3 DLC on one disc) is on sale for $20. Borderlands is an FPS RPG with a focus on collecting loot.

For one week only you can get both Scribblenauts DS games for $30. Part of the Gamestop power saver sale.
