Good games not mentioned yet:
Ace Attorney series (Phoenix Wright, Apollo Justice)
Castlevania games
Kirby Canvas Curse
Meteos
Puzzle Quest: Challenge of the Warlords
Clubhouse Games (a.k.a. 42 All-Time Classics)
Very good handheld iterations of PC strategy games:
Age of Empires: Age of Kings/Age of Mythologies
Civilization Revolution
Anno 1701
(unlike their PC counterparts, AoE and 1701 are not real time but turn-based on DS, but still great)
